ルピストンポンプ・モーター。 An actuator in which a swash plate causes a piston to reciprocate within a plurality of cylinders in the axial direction, which are bored in a cylinder block that rotates by contacting a valve plate having an intake port and a discharge port and engaging with a shaft. In a dial piston pump motor, a pressure oil line equipped with a pressure reducing valve and an accumulator is connected from a separate hydraulic power source to a conduit that opens on the sliding surface between the suction port and the discharge port of the valve plate. Features an axial piston pump motor.
