Siphon generator
A siphon is provided that includes a conduit assembly. A suction device is connected to the conduit assembly for evacuating air from the conduit assembly, allowing a fluid to be drawn into the conduit assembly. A closure mechanism is moveable from an open position, which allows the fluid to flow therepast, to a closed position, which prevents the fluid from flowing therepast.
The present invention relates generally to a siphon for removing a fluid from an originating vessel, and particularly to a siphon containing a suction device for drawing a fluid into the siphon and a closure mechanism for allowing or preventing the fluid from flowing therepast.
BACKGROUND OF THE INVENTIONIt is sometimes desirable to siphon or draw a fluid from an originating vessel, which originally contains the fluid. In some instances it is desirable to transfer the fluid from the originating vessel to a separate receiving vessel. In other instances it is merely desired to partially or completely empty the fluid from the originating vessel, in which case it is not necessary to transfer the fluid to a separate receiving vessel and the fluid may instead be “emptied” onto a ground surface.
Some siphons include a conduit having a pump attached thereto which initiates a drawing of a fluid from an originating vessel and into the conduit. However, these siphons typically include an open end through which the fluid to be siphoned exits. Therefore, in order to stop a flow of the fluid through the open end of the siphon, either the open end of the siphon is occluded, such as by a user's finger, or the conduit is pinched or “kinked” in order to occlude another section of the conduit. This often results in an imprecise transfer of a desired amount of the fluid, or a “messy” transfer of the fluid, such as when the fluid is being transferred to a separate receiving vessel or multiple receiving vessels.
Accordingly, a need exists for a siphon including a conduit having a suction device attached thereto for evacuating air from the conduit, allowing a fluid to fill the conduit so that a siphoning can begin; and a closure mechanism for allowing or preventing the fluid from flowing therepast.
SUMMARY OF THE INVENTIONIn one embodiment, the present invention is a siphon that includes a conduit assembly. A suction device is connected to the conduit assembly for evacuating air from the conduit assembly, allowing a fluid to be drawn into the conduit assembly. A closure mechanism is moveable from an open position, which allows the fluid to flow therepast, to a closed position, which prevents the fluid from flowing therepast
In another embodiment, the present invention is a siphon that includes a conduit assembly composed of a flexible hollow tubing and including a first conduit connected to a second conduit at a juncture that forms a high point of an inverted U or V shape. A suction device is connected adjacent to the juncture of the first and second conduits for evacuating air from the conduit assembly, allowing a fluid to be drawn into the conduit assembly. A one-way valve is disposed between the juncture of the first and second conduits and the suction device. The one-way valve allows the fluid to flow toward the juncture of the first and second conduits, while preventing the fluid from flowing toward the suction device. A closure mechanism is moveable from an open position, which allows the fluid to flow therepast, to a closed position, which prevents the fluid from flowing therepast.
BRIEF DESCRIPTION OF THE DRAWINGS
As shown in
Adjacent ends 14A-16A of the first, second and third conduits 14-16 are connected to each other via a hollow T-shaped connector 20, a cross-section of which is shown in
A second end 16B of the third conduit 16 is connected to a suction device 28, such as a pump mechanism or a low or negative pressure source. The suction device 28 creates a suction for evacuating air or another gas from the first and second conduits 14 and 15, allowing a fluid to fill the first and second conduit 14 and 15 so that a siphoning can begin. Note, to avoid duplicity only the evacuation of air is discussed below, however, it is to be understood that a gas other than air may be evacuated by the siphon 10 of the present invention. In the embodiment of
In one embodiment, the conduits 14-16 are each composed of a flexible yet sturdy material, such as a hollow, open ended, braided PVC (polyvinyl chloride) tubing, as shown for example in
The closure mechanism 26 is movable from an open position (
As shown in
As shown in
As such, when the second end 14B of the first conduit 14 is inserted into an originating vessel 24 having a fluid 22 disposed therein, the negative pressure or suction created by the hand pump 28 tends to draw the fluid 22 away from the originating vessel 24 and into the first conduit 14 of the conduit assembly 12. Continued depressing of the intermediate section 28C of the hand pump 28 allows more fluid 22 to be drawn from the originating vessel 24 to form a fluid flow 42 (indicated by the arrows in
Referring again to
A method of using the siphon 10 according to one embodiment of the invention placing the closure mechanism 26 in a closed position, such as by rotating the ball valve 38 of the closure mechanism 26 of
Once the fluid has filled the conduits 14 and 15 up to the second end 15B of the second conduit 15 at the juncture of the closure mechanism 26 and the second conduit 15, continued suction from the suction device 28 causes fluid to flow through the T-shaped connector 20 and into the third conduit 16. At the point where the fluid has filled the first and second conduits 14 and 15 up to the juncture of the closure mechanism 26 and the second conduit 15, the suction from the suction device 28 may be stopped, and a siphoning action may begin by moving the closure mechanism 26 from the closed position to an open position.
Any one of a variety of methods may be used to determine when to stop the suction from the suction device 28. For example, if the third conduit 16 is composed of a transparent material, a user may continue to allow the suction device 28 to produce the suction until the user visually determines that the fluid has begun to enter the third conduit. Alternatively, a user may continue to allow the suction device 28 to produce the suction until the fluid begins to exit through an open end of the suction device 28. In still another alternative, in embodiments where the first one-way valve 30 is incorporated, an indicator (such as a visual indicator or an electrical indicator) may be used to signal to the user that the fluid has reached the first one-way valve 30. In an embodiment where the first one-way valve 30 is used and the suction device 28 is a hand pump, when the fluid reaches the first one-way valve 30, the first one-way valve 30 closes, preventing the intermediate section 28C of the hand pump 28 from being depressed. In an embodiment where the first one-way valve 30 is used and the suction device is a motorized pump (such as that shown in
It is typically undesirable to allow the fluid to exit the third conduit 16 or the suction device 28 attached thereto. As such, openings in the suction device 28 may be occluded to prevent the fluid from flowing therepast. For example, in the embodiment of
It may be desired to position the second end 26B of the closure mechanism 26 adjacent to a receiving vessel 34 (see
In such a situation, the closure mechanism 26 allows for an easy transfer of the fluid by simply drawing fluid into the first and second conduits 14 and 15 (by use of the suction device 28 as described above) with the closure mechanism 26 in the closed position; placing the second end 26B of the closure mechanism 26 over an open end of the receiving vessel 34; moving the closure mechanism 26 to the open position allowing the siphoning to begin and the fluid to enter the receiving vessel 34; and moving the closure mechanism 26 to a closed position when a desired amount of the fluid has entered the receiving vessel 34. It may be desired to then empty the fluid remain in the first and second conduits 14 and 15 back into the originating vessel 24. This may be accomplished by simply moving the second end 15B of the second conduit 15 to a position above the second end 14B of the first conduit 14. When this occurs the fluid will automatically flow back into the originating vessel 24. In embodiments where the conduits 14-16 are composed of a rigid material the second conduit 15 may be attached to the first and/or third conduits 14 and 16 by a swivel joint, allowing the second end 15B of the second conduit 15 to be raised or lowered relative to the second end 14B of the first conduit 14.
In situations where it is desired to simply remove or “empty” fluid 22 from the originating vessel 24, the second end 26B of the closure mechanism 26 may be positioned adjacent to a ground surface which is lower then the fluid level in the originating vessel to allow the fluid 22 from the originating vessel 24 to be “emptied” onto the ground surface.
An open end of the suction device 28 may be occluded to prevent the fluid from flowing therepast by any one of a variety of methods. For example,
In the embodiment of
In the embodiment of
In the embodiment of
In addition or in the alternative, the third conduit 16 may include a first one-way valve 30 (see
In addition, the first one-way valve 30 may allow an airflow to flow therepast in a direction toward the suction device 28, but prevent an airflow to flow therepast in a direction toward the T-shaped connector 20. In one embodiment, the first one-way valve 30 is a “floater” check valve. Although in other embodiments, the first one-way valve 30 may be any valve appropriate to performing the above described function of allowing an airflow in a desired direction, while preventing a fluid flow in that same desired direction. This valve may or may not additionally prevent an airflow therepast in a direction toward the T-shaped connector 20.
Alternatively, the third conduit 16 may include a first one-way valve 30, which functions to allow an airflow toward the suction device 28, and to prevent a fluid flow in the same direction; and a second one-way valve 80, which functions to prevent an airflow to flow therepast toward the T-shaped connector 20. The second one-way valve 80 may be a check valve, a hand valve or any other device capable of performing the above described function.
In addition, although the suction device 28 is described above as being a hand pump, in other embodiments the suction device 28 may be a motorized pump, or a piston and cylinder arrangement, among other types of pumps and/or suction devices. For example, in the embodiment of
In the embodiment of
Although the fluid 22 in the originating vessel 24 has not been specified, the fluid 22 may be any appropriate fluid, such as water or gasoline among other appropriate fluids.
The preceding description has been presented with reference to various embodiments of the invention. Persons skilled in the art and technology to which this invention pertains will appreciate that alterations and changes in the described structures and methods of operation can be practiced without meaningfully departing from the principle, spirit and scope of this invention.
