Abstract
A hydraulic jack including a load cylinder, a pump, a release valve and a flow regulator. The pump is configured to provide pressurized fluid to the load cylinder. The release valve is in fluid communication with the pressurized fluid. The flow regulator is configured to alter a flow path of the fluid therethrough as an inverse function of a pressure drop of the fluid across the flow regulator. The fluid regulator being in fluid communication with the release valve.
Claims18
A hydraulic jack, comprising:
- a load cylinder;
- a pump configured to provide pressurized fluid to said load cylinder;
- a release valve in fluid communication with the pressurized fluid;
- and
- a flow regulator configured to alter a flow path of the fluid therethrough as an inverse function of a pressure drop of the fluid across said flow regulator, said flow regulator being in fluid communication with said release valve, said flow regulator includes a plurality of ports, a select number of said plurality of ports having the fluid pass therethrough dependent upon the pressure drop.
A hydraulic system to provide for a release of pressurized fluid, comprising:
- a release valve in fluid communication with the pressurized fluid;
- and
- a flow regulator configured to alter a flow path of the fluid therethrough as an inverse function of a pressure drop of the fluid across said flow regulator, said flow regulator being in fluid communication with said release valve, said flow regulator includes a plurality of ports, a select number of said plurality of ports having the fluid pass therethrough dependent upon the pressure drop.
A method of retracting a hydraulic cylinder under a load, the method comprising the steps of:
- releasing a valve in fluid communication with pressurized fluid in the cylinder;
- and
- altering a flow path of the fluid through a flow regulator as a pressure drop of the fluid across said flow regulator changes, said flow regulator being in fluid communication with said valve said flow regulator includes a plurality of ports, a select number of said plurality of ports having the fluid pass therethrough dependent upon the pressure drop.
