Abstract:
A hydraulic power unit for a floor jack that includes a secondary safety check valve (SSCV) to provide additional leakdown protection, backing up the main check valve. The SSCV acts as a safety measure to prevent the unit from losing load bearing capabilities if the main check valve fails. In addition, the SSCV acts as a means to prevent debris from entering the main check valve, thereby reducing the chance for failure due to an obstruction.

Claim (Index 7):
A hydraulic power unit, comprising:\n a valve block, the valve block including a fluid reservoir, and having a lift piston assembly extending from a first side and a fluid cylinder in a second side opposite the first side; a first through-bore in the valve block extending from an external surface of the valve block to the lift piston assembly; a release passage in the valve block, fluidly connecting the first through-bore to the fluid reservoir; a release valve disposed in the first through-bore and adapted to close the release passage during operation of the hydraulic power unit; a vertical passage in the valve block, the vertical passage including first and second check valves; a first horizontal passage in the valve block, fluidly connecting the fluid cylinder to the vertical passage, to communicate fluid between the fluid cylinder and the first and second check valves; a second horizontal passage in the valve block, fluidly connecting the lift piston assembly to the vertical passage, wherein the first check valve is between the first and second horizontal passages; and a secondary safety check valve in the second horizontal passage, the secondary safety check valve adapted to open in response to pressure received through the first check valve and transfer fluid from the fluid cylinder to the lift piston assembly.
