とする油圧調整弁。 The valve body has a cylindrical valve body with an inlet port and an outlet port formed in axially spaced sides and is closed at both ends, and an annular recess for communicating between the inlet port and the outlet port. A spool valve body is fitted to the valve body so as to be slidable in the axial direction, and one end wall of the valve body and the spool valve body are connected to an outlet port to introduce hydraulic pressure to bias the spool valve body in the closing direction. The degree of communication between the pilot hydraulic chamber defined between, the spring interposed between the other end wall of the valve body and the spool valve body to bias the spool valve body in the opening direction, and the inlet port and the outlet port. In a hydraulic pressure regulating valve that includes a constriction section constituted by a valve body and a spool valve body to control 1. A hydraulic pressure regulating valve comprising: an inlet port side edge of a recess;
