トン型油圧モータ。 □[Scope of Claim for Utility Model Registration] An introduction and outlet side for supplying and discharging hydraulic oil to a cylinder block that rotates via a piston that reciprocates according to the tilt angle of the swash plate when hydraulic oil is supplied and discharged. In a piston-type hydraulic motor having a valve plate in which both ports are formed, notches are formed at the ends of both claw-shaped ports, and the valve plate on the axis of symmetry between these two ports communicates with the hydraulic tank. A through hole with a small diameter inscribed in the outer periphery of both ports is bored, and a blind part is provided between the through hole and the notch so that the cylinder port in the cylinder block does not communicate with them at the same time. A piston type hydraulic motor characterized by: □
