Claims

[Scope of utility model registration request]

The casing has a cam surface formed on the inner peripheral wall of the casing,
A distribution shaft having a pair of suction/exhaust ports is rotatably attached to the casing eccentrically with respect to the cam surface, and a rotor disposed in the casing is fitted into the tip of the distribution shaft. The rotor is rotatably supported, a plurality of cylinders are radially bored in the rotor and communicate intermittently with each of the suction/exhaust ports, and a piston is slidably installed in each cylinder. The shoe is swingably attached to the shoe slidingly in contact with the cam surface, and the distribution shaft is provided with a distribution shaft rotation mechanism for rotating the distribution shaft, and the distribution shaft is provided with a distribution shaft rotation mechanism for rotating the distribution shaft, and the distribution shaft is provided with a distribution shaft rotating mechanism for rotating the distribution shaft. A flow path connecting the high-pressure cylinder and the low-pressure side port, and a flow path connecting the low-pressure cylinder and the high-pressure side port are provided, and each path communicates between the respective cylinders and ports, respectively. A radial piston type hydraulic rotating machine equipped with a control valve that shuts off.
