CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent Applications, Ser. No. 60/510,335; entitled “Fuel Pump Override System” filed Oct. 10, 2003.

TECHNICAL FIELD OF THE INVENTION

The present invention relates generally to the field of vehicle fuel systems and, more particularly, to a vehicle fuel pump override system.

BACKGROUND OF THE INVENTION

There are times when a vehicle's fuel system fails, such as a failure of a fuel pump, failure of the fuel pump relay, clogged fuel filter, bad fuel, etc. In these circumstances, there is very little the operator can do but to have the vehicle towed to a maintenance facility. Moreover, once the vehicle is at the maintenance facility, the vehicle must be manually pushed in and out of the maintenance bay, which usually takes three or more mechanics away from their assigned duties. Alternatively, the vehicle can be started and driven by pouring fuel directly into the engine, which also takes at least two mechanics and is obviously more dangerous. In the case where the fuel is thought to be bad, the fuel tank must be drained and refilled to determine whether that was the cause of the problem and to fix it. Accordingly, there is a need for a fuel pump override system that is easy to use, is inexpensive and enables a vehicle having a failed fuel system to be run safely and temporarily.

SUMMARY OF THE INVENTION

The present invention provides a fuel pump override system that is easy to use, is inexpensive and enables a vehicle having a failed fuel system to be run safely and temporarily. More specifically, the present invention is used to supply the required fuel pressure and fuel to allow a vehicle to run temporarily for movement or transport that otherwise would have to be towed, pushed or otherwise moved due to a bad fuel delivery system, such as a failure of a fuel pump, failure of the fuel pump relay, clogged fuel filter, bad fuel, etc.

The present invention provides a liquid pressurization and release apparatus having a housing with a discharge aperture positioned at one end of the housing and a slidable disk disposed within the housing to form a chamber suitable to fill, pressurize and release a liquid, a compression mechanism attached to the slidable disk and a tensioning mechanism coupled to the slidable disk to pressurize and maintain pressure in the chamber.

One embodiment of the present invention provides an apparatus for pressurization and release of a liquid including a housing having a first end having a notched aperture and a second end having a discharge aperture, a slidable disk disposed within the housing to form a fluid displacement chamber, a spring disposed in the housing between the slidable disk and the first end of the housing, such that compressing the spring draws into the fluid displacement chamber and decompressing the spring pressurizes the liquid in the fluid displacement chamber and a rod attached to the slidable disk and engaging the notched aperture, to compress the spring and decompress the spring.

The present invention also provides a method of pressurizing and releasing a liquid into a system including the steps of providing a pressurization and release apparatus having an aperture, attaching the aperture of the pressurization and release apparatus to a system and releasing the pressurized liquid into the system. The pressurization and release apparatus may include a housing having an aperture, a slidable disk disposed within the housing to form a chamber suitable to fill, pressurize and release a liquid, a compression mechanism attached to the slidable disk and a tensioning mechanism coupled to the slidable disk.

DETAILED DESCRIPTION

While the production and application of various embodiments of the present invention are discussed in detail below in relation to a fuel pump override system, it should be appreciated that the present invention provides many applicable inventive concepts that may be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention.

The present invention provides a fuel pump override system that is easy to use, is inexpensive and enables a vehicle having a failed fuel system to be run safely and temporarily. More specifically, the present invention is used to supply the required fuel pressure and fuel to allow a vehicle to run temporarily for movement or transport that otherwise would have to be towed, pushed or otherwise moved due to a bad fuel delivery system, such as a failure of a fuel pump, failure of the fuel pump relay, clogged fuel filter, bad fuel, etc.

For example, FIG. 1 depicts a perspective view of one embodiment of the present invention. The fuel pump override system 100 includes three basic functional components: a pressure control section 102, a fuel compression section 104 and a fuel connection/valve section 104. An exposed perspective view of the fuel pump override system 100 is shown in FIG. 2. The fuel pump override system 100 includes a cylinder 110, an open/close valve 112 connected to a first end 114 of the cylinder 110, a fuel connector 116 connected to the open/close valve 112, a fuel bladder 118 disposed within the cylinder 110 having one end 120 connected to the open/close valve 112 and a compression disc 122 disposed within the cylinder 110 and connected to the other end 124 of the fuel bladder 118. The fuel pump override system 100 also includes a spring 126 disposed within the cylinder 110 between the compression disc 122 and a second end 128 of the cylinder 110, a spring tension adjuster 130 for varying the tension of the spring 126, a retract rod 132 (threaded, notched or with holes) connected to the compression disc 122 and extending out through the second end 128 of the cylinder 110, and a torque control 134 moveably connected to the retract rod 132 outside of the cylinder 110. The fuel pump override system 100 may also include one or more handles, legs or an anchor 136 connected to the exterior of the cylinder 110 to allow the device 100 to rest on the ground or be secured to a vehicle. In one example, the cylinder 110 is three inches in diameter, ten inches long and holds about one quart of fuel. Other sizes can be used.

Now referring to FIG. 3, a block diagram of the present invention 312 connected to a fuel system 300 of a vehicle is shown. The vehicle fuel system 300 includes a fuel tank 302 connected to a fuel pump 304 via fuel line 306 and a fuel distribution system 308 connected to the fuel pump 304 via fuel line 310. Whenever the fuel delivery system 300 fails due to a failure of a fuel pump 304, failure of the fuel pump relay, clogged fuel filter, broken fuel line 306, suspected bad fuel, or other type of fuel supply/flow related failures, the fuel pump override device 312 (see 100 in FIG. 1) is connected to the fuel pressure test valve or shredder valve 316 via temporary fuel line 314. In the case where the fuel is thought to be bad, the fuel pump is also disabled. The fuel pump override device 312 delivers fuel at the appropriate pressure so that the vehicle can be started and run for a certain period of time.

Referring now to FIG. 4, an exposed side view of another embodiment of the present invention is shown. The fuel pump override system 400 includes a cylinder 110, an open/close valve 112 connected to a first end 114 of the cylinder 110, a fuel connector 116 connected to the open/close valve 112, a fuel pressure regulator 408 connected to the open/close valve 112, a fuel compression chamber 402 disposed within the cylinder 110 between the first end 114 of the cylinder 110 and a piston 404. The piston 404 includes one or more o-rings 406 at the interface with the cylinder 110 to prevent leakage of fuel from the fuel compression chamber 402. A spring 126 is disposed within the cylinder 110 between the piston 404 and a second end 128 of the cylinder 110. The fuel pump override system 400 also includes a spring tension adjuster 130 for varying the tension of the spring 126, a retract rod 132 (threaded, notched or with holes) connected to the piston 404 and extending out through the second end 128 of the cylinder 110, a torque control 134 moveably connected to the retract rod 132 outside of the cylinder 110. The pressure regulator 408 typically will reduce the 60 psi in the cylinder 110 to whatever pressure is recommended for the vehicle, e.g., 20 psi. The vehicle manufacturers provide recommended fuel pressure ranges for each vehicle. Accordingly, the present invention can be used safely with any make and model of vehicle.

Now referring to FIG. 5, an exposed side view of another embodiment of the present invention is shown. The fuel pump override system 500 includes a cylinder 110, an open/close valve 112 connected to a first end 114 of the cylinder 110, a fuel connector 116 connected to the open/close valve 112, a fuel pressure regulator 408 connected to the open/close valve 112, a fuel compression chamber 402 disposed within the cylinder 110 between the first end 114 of the cylinder 110 and a piston 404. The piston 404 includes one or more o-rings 406 at the interface with the cylinder 110 to prevent leakage of fuel from the fuel compression chamber 402. The fuel pump override system 500 also includes a spring 126 disposed within the cylinder 110 between the piston 404 and a second end 128 of the cylinder 110, a spring tension adjuster 130 for varying the tension of the spring 126, a retract rod 132 (threaded, notched or with holes) connected to the piston 404 and extending out through the second end 128 of the cylinder 110, a torque control trigger 502 moveably connected to the retract rod 132 outside of the cylinder 110.

Referring now to FIG. 6, an exposed side view of another embodiment of the present invention is shown. The fuel pump override system 600 includes a cylinder 110, an open/close valve 112 connected to a first end 114 of the cylinder 110, a fuel connector 116 connected to the open/close valve 112, a fuel pressure regulator 408 connected to the open/close valve 112, a fuel compression chamber 402 disposed within the cylinder 110 between the first end 114 of the cylinder 110 and a piston 404. The piston 404 includes one or more o-rings 406 at the interface with the cylinder 110 to prevent leakage of fuel from the fuel compression chamber 402. The fuel pump override system 600 also includes a spring 126 disposed within the cylinder 110 between the piston 404 and a second end 128 of the cylinder 110, a spring tension adjuster 130 for varying the tension of the spring 126, a retract rod 132 (threaded, notched or with holes) connected to the piston 404 and extending out through the second end 128 of the cylinder 110, a torque control handle 602 moveably connected to the retract rod 132 outside of the cylinder 110.

Now referring to FIG. 7, a flow chart 700 of how the present invention is used. Fuel is first loaded into the fuel override device 100, 312, 400, 500 or 600 by attaching a siphon hose to the connecter 116 of the fuel override device 100, 312, 400, 500 or 600 and placing the other end of the siphon hose in a container of fuel. The open/close valve 112 is moved to the open position and the retract rod 132 is retracted to siphon fuel into the fuel override device 100, 312, 400, 500 or 600 until the bladder 118 or fuel compression area 402 are completely filled. The open/close valve 112 is then closed, the siphon hose is removed from the fuel container and detached from the fuel override device 100, 312, 400, 500 or 600. A fuel distribution line or temporary fuel line is attached to the connector 116 and the device 100, 312, 400, 500 or 600 is now ready to use.

In order to use the fuel override device 100, 312, 400, 500 or 600, air is bled from the temporary fuel line 314 in block 702 and the temporary fuel line 314 is connected to the shredder valve 316 of the fuel pump 304 in block 704. All of the retracted pressure on the fuel override device 100, 312, 400, 500 or 600 is released in block 706 and the open/close valve 112 is opened in block 708. The vehicle can now be started in block 710 and driven to a maintenance facility or into/out of a maintenance bay. Typically, the device 100, 312, 400, 500 or 600 will be secured to the vehicle or set in a position using the handle, legs or anchor 136 so that the fuel connection will not be broken or stressed.

Referring now to FIGS. 8A, 8B and 8C, perspective views of another embodiment of the present invention are shown. The fuel pump override system 100 includes a cylinder 110, a fuel connector 116 connected to a first end 114 of the cylinder 110, a piston 804 having one or more o-rings 806 positioned around the circumference of the piston 804 disposed within the cylinder 110, a spring 126 disposed within the cylinder 110 between the piston 804 and a second end 128 of the cylinder 110, a spring tension adjuster 130 for varying the tension of the spring 126, a retract rod 132 (threaded, notched or with holes) connected to the piston 804 and extending out through the second end 128 of the cylinder 110, a gear box 834 engaging the retract rod 132 and attached to the exterior of the cylinder 110. FIG. 8a depicts a handle or leg 136 connected to the exterior of the cylinder 110 to allow the device 100 to rest on the ground, held or be secured to a vehicle. Alternatively, other apparatus may be attached, e.g., legs, magnetic areas or an anchor not shown. The fuel pump override system 100 may also have a house 808 attached to the fuel connector 116. In one example, the cylinder 110 is three and a quarter inches in diameter, twelve inches long and holds over about one quart of fuel. Other embodiments may use different diameters and the lengths to adjust the capacity of the invention to other applications or needed.

In one embodiment, the gearbox 834 may be used to engage the retracting rod, whereby operating the gearbox 834 in turn operated the retract rod 132. The gearbox 834 may use gears (e.g., spur gears, helical gears, bevel gears, worm gears, rack and pinion gears or combinations thereof) of differing size and ratios depending on the needs of the application, e.g., different ratios to allow higher compression springs to be used and, thus, to produce higher pressures. Additionally, the gearbox 834 may be driven manually or through power (e.g., battery powered, powered by the electrical system of the vehicle) supplied to a motor, which in turn drives the gears of the gearbox 834.

The present invention provides a liquid pressurization and release apparatus 100 including a housing 110 with a discharge aperture (not shown) positioned on one end, a slidable disk 106 disposed within the housing 110, a compression mechanism and a tensioning mechanism. The housing 110 may have a discharge aperture (not shown) at one end to allow fluid movement between the housing 110 and the system. The discharge aperture (not shown) may have a valve 104 attached to control the flow or seal the liquid pressurization and release apparatus 100. The discharge aperture (not shown) may also have different connections 104 to allow the connection of the liquid pressurization and release apparatus 100 to a variety of systems and positions within the system, e.g., fuel pump, fuel line, fuel rail and the like.

The slidable disk 404 is disposed within the housing 110 and forms a chamber 402 suitable to fill, pressurize and release a liquid. The movement of the slidable disk 404 functions to change the volume of the chamber 402. The slidable disk 404 has one or more rings 406 positioned around the slidable disk 404 and between the inner walls of the housing 110, whereby the chamber 402 is partially sealed. The rings 406 may be o-rings, self lubricating o-rings or other mechanism suitable to create a partial seal between the slidable disk 404 and the housing 110. Alternatively, the slidable disk 404 may be attached to an expandable bladder 118 that is connected to the housing 110. The movement of the slidable disk 404 may cause the movement of the fuel bladder 118 and the formation of a chamber 402 to pressurization and release liquids.

The compression mechanism is attached to the slidable disk 404. The compression mechanism allows the movement of the slidable disk 404, thus changing the volume of the chamber 402. The compression mechanism may be in a variety of forms. The compression mechanism may be a threaded or notched rod 132 attached to the slidable disk 404 and extending through a threaded aperture (not shown) in the housing 110. The rod 132 may have a handle (not shown) attached to facilitate the rotation of the rod 132 and thereby move the slidable disk 404. The compression mechanism may also include a threaded rod 132 attached to the slidable disk 404 and extending through an aperture (not shown) in the housing 110 and in connection with a gearbox 834. The gearbox 834 may use gears (e.g., spur gears, helical gears, bevel gears, worm gears, rack and pinion gears or combinations thereof) of differing size and ratios depending on the needs of the application, e.g., different ratios to allow higher compression springs to be used to produce higher pressures. Additionally, the gearbox 834 may be driven manually or through power (e.g., battery powered or powered by the electrical system of the vehicle) supplied to a motor, which in turn drives the gears of the gearbox 834. The compression mechanism may also use a hydraulic mechanism to move the rod 132 attached to the slidable disk 404. Additionally, the compression mechanism may be a gear system or motor located within the housing 110 with a control to activate compression or movement of the slidable disk 404. The present invention also has a tensioning mechanism in contact with the slidable disk 404, wherein the tension created by the tensioning mechanism is used to pressurize and maintain pressure in the chamber 402.

The tensioning mechanism may be a single spring 126 or more than one springs 126 configured in a variety of ways. The compression of the tensioning mechanism results in a pressure being exerted on the slidable disk 404 and in turn on the liquid in the chamber 402. The tensioning mechanism is coupled to the slidable disk 404, in a manner that allows the tensioning mechanism to be in contact with the slidable disk 404 or connected to the slidable disk 404. Although it is not necessary for the tensioning mechanism to be in contact with the slidable disk 404 at all times, e.g., when the apparatus 100 is not in operation. In one embodiment, the tensioning mechanism may be one or more springs 126. The pressure exerted by the spring 126 results in the liquid being at a specific pressure, e.g., between about 5 and 100 psi. The spring 126 may be rated between about 400 and 1600 pounds depending on the particular needs (e.g., psi) of the specific application. The tensioning mechanism may also be pneumatic mechanism, a hydraulic mechanism, an electric mechanism, a magnetic mechanism, a mechanical mechanism or combinations thereof, wherein the tensioning mechanism results in a pressure being applied to the liquid in the chamber 402. The pressure resulting from the tensioning mechanism may result in a substantially constant pressure produced by the apparatus 100.

The present invention also provides an apparatus 100 for the pressurization and release of a liquid including a housing 110, a slidable disk 404 a spring and a rod 132 attached. The housing 110 has a first end 114 that has a threaded aperture (not shown) and a second end 128, which has a discharge aperture (not shown) for release of a pressurized liquid. The discharge aperture (not shown) may be adapted to fit a valve 104 or fitting to allow connection to a variety of liquid systems (e.g., methanol, diesel, gasoline, kerosene, water, hydrocarbon and the like) and connect at a variety of locations in the system, e.g., the fuel rail, fuel pump, fuel line and the like.

The present invention also provides a slidable disk 404 disposed within the housing 110. The movement of the slidable disk 404 forms a fluid displacement chamber 402 between the second end 128 of the housing 110 and the slidable disk 404. In another embodiment, a fuel bladder 118 is connected to the second end 128 of the housing 110 and the slidable disk 404. The movement of the slidable disk 404 expands the fuel bladder 118 to form a fluid displacement chamber 402 between the second end 128 of the housing 110 and the slidable disk 404. Alternatively, the slidable disk 404 may be attached to an expandable bladder 118 that is connected to the housing 110. The movement of the slidable disk 404 may cause the movement of the fuel bladder 118 and the formation of a chamber 402 to pressurization and release liquids.

A spring 126 may be disposed within the housing 110 between the slidable disk 404 and the first end 114 of the housing 110. The compression of the spring 126 results in a pressure being exerted on the slidable disk 404 and in turn on the liquid in the chamber 402. The spring 126 may be an individual spring or multiple springs in a variety of configurations. The pressure exerted by the spring 126 results in the liquid being at a specific pressure, e.g., between about 5 and 100 psi. The spring rated may be rated between about 400 and 1600 pounds depending on the particular needs (e.g., psi) of the specific application. The compression of the spring 126 moves the slidable disk 404 and draws fluid into the fluid displacement chamber 402. The decompression of the spring 126 results a pressure being applied to the slidable disk 404 and the pressurization the liquid in the fluid displacement chamber 402.

The present invention also includes a rod 132 connected to the slidable disk 404 and engaging the threaded aperture (not shown) located on the first end 114 of the housing 110, whereby engaging the notched aperture (not shown) moves the slidable disk 404 and compresses the spring 126 and disengaging the notched aperture (not shown) releases the slidable disk 404 decompresses the spring 126. The contents of the chamber 402 are then pressurized as a result of the pressure from the spring 126. In some embodiments, the rod 132 may have a handle (not shown) attached to aid in the rotation of the rod 132 and in-turn the movement of the slidable disk 404. Alternatively, the notched aperture (not shown) may be a part of a gearbox 834 attached to the housing 110, which provides a mechanical advantage to the movement of the rod and the slidable disk 404. The gearbox 834 may use gears (e.g., spur gears, helical gears, bevel gears, worm gears, rack and pinion gears or combinations thereof) of differing size and ratios depending on the needs of the application, e.g., different ratios to allow higher compression springs to be used to produce higher pressures. Additionally, the gearbox 834 may be driven manually or through power (e.g., battery powered or powered by the electrical system of the vehicle) supplied to a motor, which in turn drives the gears of the gearbox 834. The compression mechanism may also use a hydraulic mechanism to move the rod 132 attached to the slidable disk 404.

The present invention also provides a method of pressurizing and releasing a liquid into a system. The method includes the steps of providing a pressurization and release apparatus 100, attaching the pressurization and release apparatus to a liquid system, and releasing contents into the system. The pressurization and release apparatus includes a housing 110 having an aperture 104, a slidable disk 404 disposed within the housing 110 to form a chamber 402 suitable to fill, pressurize and release a liquid, a compression mechanism attached to the slidable disk 404, and a tensioning mechanism coupled to the slidable disk 404 to pressurize and maintain pressure in the chamber 404.

The compression mechanism is attached to the slidable disk 404. The compression mechanism allows the movement of the slidable disk 404, thus changing the volume of the chamber 402. The compression mechanism may be in a variety of forms. The compression mechanism may be a threaded or notched rod 132 attached to the slidable disk 404 and extending through a threaded or notched aperture (not shown) in the housing 110. The rod 132 may have a handle (not shown) attached to facilitate the rotation of the rod 132 and thereby move the slidable disk 404. The compression mechanism may also include a threaded or notched rod 132 attached to the slidable disk 404 and extending through an aperture (not shown) in the housing 110 and in connection with a gearbox 834. The gearbox 834 may use gears (e.g., spur gears, helical gears, bevel gears, worm gears, rack and pinion gears or combinations thereof) of differing size and ratios depending on the needs of the application, e.g., different ratios to allow higher compression springs to be used to produce higher pressures. Additionally, the gearbox 834 may be driven manually or through power (e.g., battery powered or powered by the electrical system of the vehicle) supplied to a motor, which in turn drives the gears of the gearbox 834. The compression mechanism may also use a hydraulic mechanism to move the rod 132 attached to the slidable disk 404. Additionally, the compression mechanism may be a gear system or motor located within the housing 110 with a control to activate compression or movement of the slidable disk 404. The present invention also has a tensioning mechanism in contact with the slidable disk 404, wherein the tension created by the tensioning mechanism is used to pressurize and maintain pressure in the chamber 402.

The tensioning mechanism may be a single spring 126 or more than one springs 126 configured in a variety of ways. The compression of the tensioning mechanism results in a pressure being exerted on the slidable disk 404 and in turn on the liquid in the chamber 402. The tensioning mechanism is coupled to the slidable disk 404, in a manner that allows the tensioning mechanism to be in contact with the slidable disk 404 or connected to the slidable disk 404. Although it is not necessary for the tensioning mechanism to be in contact with the slidable disk 404 at all times, e.g., when the apparatus 100 is not in operation. In one embodiment, the tensioning mechanism may be one or more springs 126. The pressure exerted by the spring 126 results in the liquid being at a specific pressure, e.g., between about 5 and 100 psi. The spring 126 may be rated between about 400 and 1600 pounds depending on the particular needs (e.g., psi) of the specific application. In other embodiments, the tensioning mechanism may also be pneumatic mechanism, a hydraulic mechanism, an electric mechanism, a magnetic mechanism, a mechanical mechanism or combinations thereof, wherein the tensioning mechanism results in a pressure being applied to the liquid in the chamber 402. The pressure resulting from the tensioning mechanism may result in a substantially constant pressure produced at the aperture by the pressurization and release apparatus 100.

The method of the present invention may further include the step of filling the pressurization and release apparatus 100 that includes attaching the pressurization and release apparatus 100 to a supply of liquid and compressing the compression mechanism whereby drawing the liquid into the chamber 402. The step of pressurizing the liquid within the pressurization and release apparatus 100 includes releasing the compression mechanism allowing the tensioning mechanism to apply pressure to the liquid contained within the chamber 404 of the pressurization and release apparatus 100.

The pressurization and release apparatus 100 may be attached to the system using the aperture (not shown) of the pressurization and release apparatus 100. The aperture (not shown) may include a valve 104 or a variety of fittings to allow the attachment of the pressurization and release apparatus 100 at a variety of points throughout the system, e.g., the fuel rail, fuel pump, fuel line and the like. The pressurization and release apparatus 100 may also be used to withdraw liquid from the system and then supply the pressurized liquid to another part of the system, e.g., attach the pressurization and release apparatus 100 to the fuel system, remove a portion of the fuel from a fuel tank, pressurize the fuel and then release the fuel to the fuel system. Additionally the pressurization and release apparatus 100 may be configured to allow connection to a variety of systems (e.g., methanol, diesel, gasoline, kerosene, water, hydrocarbon and the like). The pressurized liquid is then releases into the system, allowing the system to obtain and use the liquid.
