ABSTRACT:
A check valve assembly is disposed in a flow path of a high pressure hydraulic actuating system between a source of pressurized fluid and a pressure responsive mechanism to limit flow to a single direction therebetween. A valve housing defines a fluid passage therethrough with a first axis therealong. The fluid passage has an annular first seat surface normal to the axis. A fitting is fixed to the valve housing and has a post directed toward fluid flow from the source of pressurized fluid. A check valve assembly slidably translates on the post between a closed position abutting the first seat surface which restricts flow toward the pressure source, and an open position spaced from the first seat surface which permits flow toward the pressure responsive mechanism. A spring disposed between the fitting and the check biases the check to the closed position.
