ストンから構成しなる油圧緩衝器。[Scope of Claim for Utility Model Registration] A hydraulic cylinder equipped with a damping force generating valve mechanism in the piston and partitioned into two oil chambers by the piston, and its external reservoir chamber are provided in the suction port of the bottom base. In a hydraulic shock absorbing mechanism in which a valve is connected via a check valve provided at a discharge port having a hollow hole in a piston rod as an oil supply path, the check valve for opening and closing the discharge port has an annular case disposed outside the discharge port. A flow path is formed by connecting the discharge port and the rod side oil chamber, and a valve body is provided at the opening of the flow path with the end surface of the case serving as a seat. A hydraulic shock absorber comprising a pilot piston that opens the valve body.

に構成してなる油圧緩衝器。 A hydraulic cylinder equipped with a damping force generating valve mechanism in the piston part and partitioned into upper and lower oil chambers by the piston part and its external reservoir chamber are connected to a suction port in the bottom base part and a discharge port in which the piston rod hollow hole is used as an oil supply path. In the hydraulic shock absorbing mechanism, a check valve that opens and closes the discharge port according to piston movement is located between the discharge port and the upper oil chamber and is energized in the direction of closing the flow path. The hydraulic shock absorber is configured to open a flow path by moving the valve in a direction that resists the urging force due to the chamber pressure of the lower oil chamber.
