The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The housing 12 has a top wall 32, a bottom wall 34 and an outside wall 36 extending between the top wall 32 and the bottom wall 34 and the outside wall 36 has a front side 38 and a back side 40. Each of the return port 16 and the supply port 14 is disposed on the back side 40 and the fill port 18 is disposed on the front side 38. The housing 12 has a grip 42 extending upwardly from the top wall 32. The grip 42 has an opening 43 extending laterally through the grip 42 and a mount tower 44 extending upwardly from a top 45 of the grip 42. Additionally, the mount tower 44 is aligned with the front side 38 of the outside wall 36 of the housing 12. A first conduit 46 is fluidly coupled between the return port 16 and the fill port 18 and a second conduit 48 is fluidly coupled to the supply port 14. The second conduit 48 intersects the first conduit 46 at a point located adjacent to the fill port 18.
A shut off valve 50 is movably integrated into the housing 12 and the shut off valve 50 is in fluid communication between the supply port 14, the return port 16 and the fill port 18. The shut off valve 50 is actuatable into a first condition defining a first fluid circuit 52 between the return port 16 and the supply port 14. Conversely, the shut off valve 50 is actuatable into a second condition defining a second fluid circuit 54 between the supply port 14 and the fill port 18. The shut off valve 50 is biased into the first condition and the shut off valve 50 is located at the intersection between the first conduit 46 and the second conduit 48. Furthermore, the shut off valve 50 includes a lever 56 for urging the shut off valve 50 between the first condition and the second condition. The shut off valve 50 may comprise a two way fluid valve of any conventional design.
A trigger 58 is movably integrated into the grip 42 and the trigger 58 is in communication with the shut off valve 50. The shut off valve 50 is actuated into the second condition when the trigger 58 is depressed. Conversely, the shut off valve 50 is biased into the first condition when the trigger 58 is not depressed. The trigger 58 is positioned in the opening 43 in the grip 42 at a point that is aligned with the mount tower 44 on the grip 42. A trigger cable 60 is coupled between the trigger 58 and the lever 56 on the shut off valve 50 thereby facilitating the lever 56 to be pivoted when the trigger 58 is depressed.
A handle 62 is provided and the handle 62 is pivotally disposed on the housing 12. The handle 62 is urgeable into an engaged position and the handle 62 is biased into a disengaged position. The handle 62 has a coupled end 64 and the handle 62 has a pivot point 66 that is pivotally attached to the mount tower 44 on the grip 42. The pivot point 66 is positioned proximate the coupled end 64 such that the handle 62 is spaced from and is oriented to angle upwardly from the top of the grip 42. Furthermore, the handle 62 has a handle pulley 68 that is aligned with the coupled end 64 and the handle pulley 68 rotates about the pivot point 66.
An inertial pump 70 is movably disposed within the housing 12 and the inertial pump 70 is in fluid communication with the supply port 14. In this way the inertial pump 70 is in fluid communication with the first container 22 when the first hose 20 is fluidly coupled between the supply port 14 and the first container 22. The inertial pump 70 is in communication with the handle 62 and the inertial pump 70 is charged when the handle 62 is urged into the engaged position to urge the fluid 24 in the first container 22 inwardly through the supply port 14. Furthermore, the inertial pump 70 urges the fluid 24 outwardly through the return port 16 when the shut off valve 50 is in the first condition. The inertial pump 70 urges the fluid 24 outwardly through the fill port 18 when the shut off valve 50 is in the second condition thereby facilitating the fluid 24 in the first container 22 to be transferred into the second container 30.
The inertial pump 70 comprises a primary shaft 72 that is rotatably disposed between a first lateral side 74 and a second lateral side 76 of the outside wall 36 of the housing 12. The inertial pump 70 includes a pair of disks 78 that each has a first side 80 and the first side 80 of each of the disks 78 is attached to the primary shaft 72 such that the primary shaft 72 is perpendicularly oriented with the first side 80. Each of the disks 78 is rotated about the primary shaft 72 when the primary shaft 72 is rotated thereby facilitating each of the disks 78 to store rotational energy of the primary shaft 72. Each of the disks 78 is comprised of a dense and rigid material, including but not being limited to steel or brass, thereby facilitating the disks 78 to generate sufficient momentum for storing rotational energy in the convention of a flywheel.
The inertial pump 70 includes a drive wheel 82 that is positioned around the primary shaft 72 such that the drive wheel 82 rotates the primary shaft 72 when the drive wheel 82 is rotated. The drive wheel 82 is positioned adjacent to the first side 80 of a respective one of the disks 78. The drive wheel 82 includes a clutch 84 which facilitates the drive wheel 82 to engage the primary shaft 72 when the drive wheel 82 is exposed to rotational torque. Furthermore, the clutch 84 facilitates the drive wheel 82 to disengage the primary shaft 72 when the drive wheel 82 is not exposed to rotational torque.
The inertial pump 70 includes a drive pulley 85 that is rotatably disposed within the housing 12. The inertial pump 70 includes a drive cable 86 attached between the handle pulley 68 integrated into the handle 62 and the drive wheel 82. The drive cable 86 extends around the drive pulley 85 thereby defining a first portion 88 of the drive cable 86 extending between the drive pulley 85. Furthermore, the handle pulley 68 is perpendicularly oriented with a second portion 90 of the drive cable 86 which extends between the drive pulley 85 and the drive wheel 82. The drive cable 86 is wrapped around the handle pulley 68 when the handle 62 is urged into the engaged position such that the drive cable 86 imparts rotational torque into the drive wheel 82. In this way the pair of disks 78 can be rotated by the primary shaft 72 for converting the rotational torque into the rotational energy stored in the disks 78.
The inertial pump 70 includes a primary gear 92 that is positioned around the primary shaft 72 such that the primary shaft 72 rotates the primary gear 92. The primary gear 92 is positioned adjacent to the first side 80 of an opposing one of the pair of disks 78 with respect to the drive wheel 82. The inertial pump 70 includes a pump 94 that is integrated into the second conduit 48 in the housing 12. The pump 94 is positioned closer to the supply port 14 than the intersection between the second conduit 48 and the first conduit 46 and the pump 94 urges the fluid 24 inwardly through the supply port 14 when the pump 94 is actuated. The pump 94 urges the fluid 24 along the first fluid circuit 52 when the shut off valve 50 is in the first condition such that the fluid 24 re-circulates in the first container 22. The pump 94 urges the fluid 24 along the second fluid circuit 54 when the shut off valve 50 is in the second condition such that the fluid 24 transfers from the first container 22 to the second container 30. The pump 94 may comprise a impeller fluid pump or other similar type of mechanical fluid pump.
The inertial pump 70 includes a secondary gear 96 that is attached to the pump 94. The secondary gear 96 enmeshes with the primary gear 92 such that the secondary gear 96 is rotated when the primary gear 92 is rotated for driving the pump 94. In this way the disks 78 can continuously drive the pump 94 when the disks 78 are rotated. Additionally, the primary gear 92 has a greater diameter than the secondary gear 96 thereby increasing the rotational speed supplied to the pump 94.
A priming pump 98 is integrated into the housing 12 and the primary pump 94 is in communication with the supply port 14. The primary pump 94 urges the fluid 24 inwardly through the supply port 14 for priming the inertial pump 70 when the priming pump 98 is manipulated and when the shut off valve 50 is biased into the first condition. The priming pump 98 is fluidly attached to the first conduit 46 in the housing 12 and the priming pump 98 includes a pumping handle 100 extending upwardly through the top wall 32 of the housing 12 for manipulating the priming pump 98. The priming pump 98 urges the fluid 24 along the first fluid circuit 52 when the shut off valve 50 is in the first condition thereby facilitating the fluid 24 to prime the pump 94 associated with the inertial pump 70. The priming pump 98 has an input 102 that is directed toward the supply port 14 and an output 104 that is directed toward the return port 16. Furthermore, the priming pump 98 comprises a suction type fluid pump such that the priming pump 98 suctionally urges the fluid 24 into the supply port 14 to prime the pump 94 associated with the inertial pump 70.
In use, the first hose 20 and the second hose 26 are inserted into the first container 22 and the third hose 28 is inserted into the second container 30. The handle 62 is repeatedly urged into the engaging position to rotate the pair of disks 78 to a sufficient velocity that the disks 78 will continue to rotate for an extended duration of time. The pumping handle 100 is urged upwardly and downwardly to prime the pump 94 associated with the inertial pump 70 to facilitate the inertial pump 70 to begin pumping the fluid 24 inwardly through the supply port 14 and outwardly through the return port 16. The trigger 58 is depressed to actuate the shut off valve 50 into the second condition thereby facilitating the inertial pump 70 to pump the fluid 24 inwardly through the supply port 14 and outwardly through the fill port 18. In this way the fluid 24 can be transferred from the first container 22 into the second container 30. Furthermore, the inertial pump 70 facilitates the fluid 24 to be pumped in any location without the use of electricity. In this way fuel from a gas can, for example, could be pumped into the fuel tank of a motorized vehicle that is being operated in a remote location.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
