弁。 In an integrated equal pressure valve that is assembled into a pump housing using a screw-in valve holder, the equal pressure valve body is divided into an upper body with a discharge side check valve spring chamber and a return side check valve seat, and a return side check valve spring chamber. It is divided into a lower body with a check valve seat on the discharge side and a check valve seat on the discharge side, and a spring receiver is built into the bottom of each of the check valve spring chambers on the discharge side and the check valve spring chamber on the return side. Internal combustion is achieved by temporarily fixing the upper and lower parts by positioning the body with multiple dowel pins and screwing machine screws into diagonal screw holes provided on the outer periphery of the upper and lower parts. Engine equal pressure valve.
