置。[Scope of Claim for Utility Model Registration] (1) It has both an outlet and an inlet port and a make-up port, and when the port pressure for both ports exceeds a specified value, pressure oil is sent to the other port via the make-up port. A hydraulic motor device is equipped with a direct-acting relief valve that allows oil to flow out, and a make-up check valve that sucks oil from a make-up port when the port pressure falls below a specified value,
A hydraulic motor device characterized in that the two sets of direct-acting relief valves and make-up check valves are integrally arranged on the same axis to form a composite relief check valve. (2) A composite relief check valve is a claim in which the check valve part is formed into a hollow cylindrical valve body, and this valve body is mounted on the outer peripheral surface of the sleeve of the relief valve part so as to be slidable in the axial direction and in a fluid-tight manner. The hydraulic motor device according to item 1.
