Abstract
A hand tool powered hydraulic fluid pump device provides hydraulic power driven by a hand tool to enhance portability. The device includes a wheeled cart with a handle for transporting a hydraulic fluid reservoir. A pump is positioned in the reservoir. A flow diverter is coupled to the pump for delivering and returning hydraulic fluid through a first fluid channel and a second fluid channel fluidly connected to a first connection port and a second connection port. A hand tool is removably couplable to a pump shaft of the pump to actuate the pump and provide hydraulic fluid to a hydraulically powered machine.
Claims12
A portable hand tool powered hydraulic fluid pump device comprising:
- a cart, said cart including:
- a base, and
- a handle coupled to said base;
- a reservoir positioned on said cart, said reservoir having an interior;
- a hydraulic fluid positioned in said interior of said reservoir;
- a pump positioned in said reservoir, said pump having a pump shaft, said pump having a first fluid circulation port, a second fluid circulation port, and a fluid input, said pump drawing said hydraulic fluid into said pump through said fluid input, said pump circulating said hydraulic fluid out of said first fluid circulation port and into said second fluid circulation port when said pump shaft is rotated;
- a flow diverter coupled to said pump, said flow diverter being coupled to said reservoir, said flow diverter including
- a first fluid channel, said first fluid channel being in fluid communication with said first fluid circulation port of said pump,
- a second fluid channel, said second fluid channel being in fluid communication with said second fluid circulation port of said pump,
- a first connection port, said first connection port being in fluid communication with said first fluid channel,
- a second connection port, said second connection port being in fluid communication with said second fluid channel, and
- wherein said pump is configured to provide the hydraulic fluid from said reservoir, through said flow diverter, and to a hydraulic operated machine connected to said first connection port and said second connection port;
- a hand tool, said hand tool being removably couplable to said pump shaft wherein operation of said hand tool rotates said pump shaft;
- and
- a flow switch couplable to said flow diverter, said flow switch including
- a first diverter connection fluidly couplable to said first connection port of said flow diverter,
- a second diverter connection fluidly couplable to said second connection port of said flow diverter,
- a first dock port configured for coupling to the hydraulic operated machine,
- a second dock port configured for coupling to the hydraulic operated machine, and
- a switch valve fluidly coupled between said first diverter connection, said second diverter connection, said first dock port, and said second dock port, and
- a lever operatively coupled to said switch valve wherein operation of said lever selectively reverses flow direction of said hydraulic fluid through said first dock port and said second dock port when hydraulically connected to said hydraulically powered machine.
