BRIEF DESCRIPTION OF THE PRIOR ART

The following is a list of prior art related to the present invention with a brief description of the present invention's differences in comparison:

In the U.S. Pat. No. 5,139,392 is a refrigerant pump which uses a swash plate as the mechanism for compressing the refrigerant. The method of driving the shaft is not mentioned. The present invention uses pneumatically driven pistons connected to a swash plate to deliver the rotation needed to drive an A/C unit.

In the U.S. Pat. No. 5,809,863 is a swash plate type axial piston pump. However, this patent is for a single axial piston pump, whereas the present invention utilizes a compressed gas powered swash plate axial piston motor to power an A/C unit.

In the U.S. Pat. No. 5,009,574 is a swash plate designed compressor. The utilization of the swash plate in this patent is different from the present invention. The present invention utilizes a swash plate to rotate and drive a shaft to power the A/C unit. The compressor of the present invention is driven by the rotating shaft.

In the U.S. Pat. No. 5,145,325 is a swash plate designed compressor. The utilization of the swash plate in this patent is different from the present invention. The present invention utilizes a swash plate to rotate and drive a shaft to power the A/C unit. The compressor of the present invention is driven by the rotating shaft.

In the European Patent EP 1384886 is a piston designed for used in a compressor. The piston is primarily used for a swash plate carbon dioxide compressor. The utilization of the swash plate in this patent is different from the present invention. The present invention utilizes a swash plate to rotate and drive a shaft to power the A/C unit. The compressor of the present invention is driven by the rotating shaft.

In the U.S. Pat. No. 4,790,727 is a compressor that is used for an A/C unit specifically. The compressor in this patent still compresses the refrigerant. However, the design of the present invention provides the rotation for a generic air conditioning unit.

In the U.S. Pat. Nos. 3,999,893, 4,781,539, and the European patent EP0569958 is a similar invention to the U.S. Pat. No. 4,790,727 mentioned above. These patents introduce a swash plate as means of compressing the refrigerant. The present invention utilizes a swash plate to power a conventional compressor.

In the U.S. Pat. No. 5,694,784 is a similar system as the above mentioned systems in that it uses a swash plate to compress the refrigerants. However, it is different in that the refrigerant is carbon dioxide. The present invention does not use a swash plate for the compressor, nor is carbon dioxide used as the refrigerant. Oxygen is used as the gas to power the pneumatic pistons, which connected to the swash rotate a shaft that powers an A/C unit.

BACKGROUND OF THE INVENTION

During a mine collapse, the working miners are required to evacuate to a mine shelter for safety. The mine shelters often provide the structural support to provide the miners a safe space to stay until rescue arrives. The mine shelters often provide the miners with the necessities for survival including carbon dioxide scrubber systems, oxygen supply, rations, and other items required for survival. However, an unaddressed and considerable problem with current mine shelters during rescue operations of mines is heat. In extreme conditions, the temperatures within a mine shelter can reach dangerous levels. The present invention is able to bring the high level temperatures in the mine rescue shelters to provide the miners with a more comfortable environment. The present invention utilizes a series of pneumatic pistons to power a swash plate and shoe. The piston's linear motions are converted into a rotational motion by the swash plate and shoe. A shaft receives the rotational energy to rotate fans and an air conditioning compressor. The fans are able to circulate air within the shelter through a heat exchanger. The heat exchanger is able to draw the heat from the shelter and transfer it to an exterior heat exchanger to be dispelled. The present invention is a safe and simple solution that provides high flow rates of conditioned air. The gas used to pressurize the pistons is the O2 gas supplied to sustain the miners until rescue. The usage of the compressed gas and multiple pistons provides the power needed to fully power an air conditioning unit.

In reference to FIG. 1 and FIG. 4, the valve system 3 works in unison with the plurality of pistons 6, the swash plate 4, and the swash plate shoe 5 to generate the require rotational energy to power the present invention. The plurality of pistons 6 generate the required linear forces that are to be converted into the rotational motions by the swash plate 4. The valve system 3 is able to regulate and distribute compressed gasses in series to the appropriate pistons for efficient generation of rotational forces. The valve system 3 comprises a first body plate 31, a second body plate 32, a plurality of valve channels 33, a cam 34, and a shoe mount 35. The first body plate 31 comprises a plurality of first valve grooves 311, a first hole 312, and a plurality of exhaust holes 313. The second body plate 32 comprises a plurality of second valve grooves 321, a second axle 73 hole, and a plurality of inlet holes 323. The first body plate 31 is secured to the second body plate 32 to create the body of the valve system 3. The combination of the first body plate 31 and the second body plate 32 allows the first valve grooves 311 and the second valve grooves 321 to define the plurality of valve channels 33. The plurality of exhaust holes 313 is holes that traverse through the first body plate 31 into the plurality of valve channels 33. Similarly, the plurality of inlet holes 323 is holes that traverse through the second body plate 32 into the plurality of valve channels 33. The first hole 312 is a hole that traverses through the center of the first body plate 31. The second hole 322 is a hole that traverses through the center of the second body plate 32. The first hole 312 and the second hole 322 are aligned and similarly sized to allow the cam 34 to be positioned through. The shoe mount 35 is positioned on the face of the second body plate 32 opposite of the first body plate 31 in concentric relationship with the second hole 322. The cam 34 is concentrically connected to the compressor axle 21. The compressor axle 21 traverses through the first hole 312 and the second hole 322 to be connected to the shoe mount 35. The plurality of spring valves 20 is positioned in the plurality of valve channels 33 to control flow of the compressed gases moving through the system.

The swash plate shoe 5 is mounted onto the shoe mount 35 for to transfer rotational energy to the compressor axle 21. The swash plate shoe 5 comprises a plate mount 51 and a mount socket 52. The plate mount 51 is connecting component that allow the swash plate 4 to be connected to the swash plate shoe 5. The plate mount 51 is positioned on an angled end of the swash plate shoe 5. The mount socket 52 is positioned on the swash plate shoe 5 opposite of the angled end. The swash plate shoe 5 is mounted onto the shoe mount 35 by means of the mount socket 52. The swash plate 4 comprises a plurality of plates 41 and a plurality of piston bearing sockets 42. Each of the plates has a plurality of holes consistent with the number of pistons. The plurality of plate are aligned and secured to each other with the plurality of holes defining the piston bearing sockets. The combination of the plurality of holes creates a spherical socket for the connection to the plurality of pistons 6.

In reference to FIG. 2, the each of the pistons of the plurality of pistons 6 comprises a cylinder chamber 61 and a piston arm 62. The plurality of pistons 6 is connected to the plurality of piston bearing sockets 42 by means of the piston arms 62 to create a low friction interface. Each piston arm 62 comprises a plate bearing 63. The plate bearings 63 are ball bearing ends on the piston arm 62 that fit directly into the plurality of piston bearing sockets 42. The ball bearing ends of the piston arm 62 provides the plurality of pistons 6 with the ability to constantly provide the linear motion at differing angles to the swash plate. The plurality of piston bearing sockets 42 is evenly distributed on the swash plate 4 in a circular arrangement. As a result, the plurality of pistons 6 is correspondingly arranged in a circular fashion onto the swash plate 4. It is important for this connection to be a low friction interface to ensure no energy is lost to heat and that all energy received by the compressed gas is translated into the rotational energy needed for the operation of the present invention.

In reference to FIG. 1, all the components are secured onto the unit frame 1 for proper operation. The compressor 2 is mounted and secured onto the compressor support 16 with the compressor axle 21 being extended towards the piston plate 17. The valve system 3 is longitudinally secured onto the drive train rack 15 in parallel relationship to the compressor support 16. The piston plate 17, similar to the valve system 3, is longitudinally secured to the drive train rack 15 in parallel relationship to the valve system 3. The piston plate 17 additionally comprises of piston mounts 171. The positioning and arrangement of the piston plate 17 allows the plurality of pistons 6 to be arranged in parallel relationship to the swash plate shoe 5. The pistons are additionally secured to the piston plate 17 to their corresponding piston mounts 171. The cylinder chamber 61s are secured to the piston mounts 171 to provide the plurality of pistons 6 with the ability to move laterally. This positioning allows for optimal conversion of the linear force provided by the pistons to rotational force through the swash plate 4 and swash plate shoe 5.

The internal heat exchanger 8 is secured onto the internal heat exchanger rack 11 in a vertical position. Similarly, the external heat exchanger 9 is secured onto the external heat exchanger rack 13 in a vertical position. The internal heat exchanger 8 and the external heat exchanger 9 are flat heat exchangers that are positioned so that the larger surfaces areas are perpendicular to the face of the internal heat exchanger rack 11 and the external heat exchanger rack 13. This type of arrangement allows the grill fins of both heat exchangers to be directed towards the sides of the present invention. As a result, the internal heat exchanger 8 and the external heat exchanger 9 are able to efficient exchange heat with the environment. To increase the efficiency of heat exchange between the internal heat exchanger 8 and the external heat exchanger 9, the fan unit 7 is used. The fan unit 7 comprises an internal fan 71, an external fan 72, a fan axle 73, and a fan pulley 74. The internal fan 71 is positioned on a first end of the axle 73 and the external fan 72 is positioned on the axle 73 opposite of the internal fan 71. The fan unit 7 is able to receive rotational energy to power the fans by means of the fan pulley 74. The fan pulley 74 is concentrically connected to the axle 73. The belt 30 is looped about the fan pulley 74 and the compressor pulley 22 to allow the sharing of the rotational energy created by the valve system 3, the swash plate 4, the swash plate shoe 5, and the plurality of pistons 6. The axle 73 is secured to the internal fan support 12 and the external fan support 14. As a result, the internal fan 71 is positioned adjacent to the internal heat exchanger 8 and the external fan 72 is positioned adjacent to the external heat exchanger 9 to create air flow through each corresponding heat exchanger. The internal heat exchanger 8 and the external heat exchanger 9 are both connected in line with the compressor 2, as well as to each other to complete the refrigerant cycling loop.

In reference to FIG. 1, to operate the present invention, the valve system 3 is required to be connected to a compressed gas tank. The compressed gas tank is connected directly to the plurality of inlet holes 323 on the first body plate 31. The plurality of valve channels 33 is connected to the cylinder chambers 61 of the plurality of pistons 6 by means of the gas tubes 10. Each valve channel is connected to each cylinder chamber 61 to allow each individual piston to act independently. In the preferred embodiment of the present invention, the compressed gas used is oxygen. To control the flow of the compressed gas, the plurality of spring valve within the plurality of valve channels 33 further comprises of an inlet channel 201 and an exhaust channel 202. Each of the spring valves 20 are normally closed and pushed towards the center of the valve system 3. Given that the cam 34 is pressing a first spring valve out, an inlet channel 201 is aligned with the corresponding inlet hole. The compressed gas is able to through inlet channel 201 into the corresponding gas tube into the cylinder chamber 61 of the corresponding piston. The compressed gas builds pressure within the cylinder chamber 61 of the piston forcing the piston arm 62 to extend. The linear force from the piston arm 62 is translated to the swash plate 4. The force applied to the swash plate 4 and the angled end of the swash plate shoe 5, causes the swash plate shoe 5 to rotate. The degree of the angled end is able to determine the amount of force from the pistons that is required for the translation into rotational force or torque. The rotation of the swash plate shoe 5 causes the rotation of the cam 34 and the compressor axle 21. This rotational energy is used to power the compressor 2 as well as the fan unit 7. The fan unit 7 is able to receive the rotational energy through the compressor pulley 22, the belt 30, and the fan pulley 74. The rotation of the cam 34 results in the release of the first spring valve. As the first spring valve is being released, the exhaust channel 202 will momentarily align with the exhaust hole. The pressure built up in the cylinder chamber 61 is released through the corresponding valve channel, through the exhaust channel 202 and out the exhaust hole. The rotation of the swash plate shoe 5 will continue and move the cam 34 to the next spring valve. The process will repeat continuously until the compressed gas supply has been depleted or if the system is shut off. Within a rescue shelter of a mine, the preferred compressed gas is oxygen. The design of the present invention allows the compressed gas to be released into the air of the rescue shelter for breathing as its compressed energy is utilized to power the unit.

As an example, the following is a description of one revolution of the swash plate 4 with four pistons. A first piston is at half through its throw and has ambient air filled inside its cylinder chamber 61. A second piston is at full extension with the compressed gas filled into its cylinder chamber 61. A third piston is at half through its throw similar to the first piston. A fourth piston is completely depressed. The cam 34 pushes open a spring valve which pressurizes the first piston. The piston pushes against the swash plate 4 which is attached to the swash plate shoe 5. The movement of the swash plate shoe 5 also changes the position of the second, third, and fourth piston. The second piston is now at the halfway position of its displacement, the third piston at its zero displacement, and the fourth piston also being at the half way position of its displacement. The spring valve associated with the first piston is aligned so that the exhaust channel 202 is aligned with the exhaust hole to release the pressurized gas. At the same time, the spring valve associated with the second piston is aligned so that the inlet channel 201 is aligned with the inlet hole for the pressurization of the second piston. This pressure will force the second piston to complete displacement and will turn the swash plate 4 another 90 degrees. This process is continued until the present invention is turned off or the supply of gas is exhausted.

The torque or rotational force produced from the rotation of the swash plate shoe 5 is transferred to the compressor axle 21. The compressor axle 21 may pass through a series of speed increasing gears and even a free wheel clutch. The compressor axle 21 will in turn run to the compressor 2 and the fan unit 7 using the belt 30 and the pulleys.

In reference to FIG. 1, an embodiment of the present invention shown is shown with four pistons, four and four valve channels 33. This design allows for a low flow rate of gas at 10 liters/min or less to be translated into high rotational torque. In other embodiments of the present invention, there may be more pistons and valve channels 33 for a smoother rotational transition. However, there must be a minimum of three pistons positioned at even intervals around the swash plate 4 and the swash plate shoe 5 for continuous rotation.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
