Claims

[Scope of utility model registration request]

A rotating shaft protruding into a casing, a cylinder block rotating together with the rotating shaft, a plurality of cylinders bored in the axial direction of the cylinder block, and a piston slidably provided inside each cylinder. , a connecting rod having one end connected to each piston and the other end swingably supported by the rotating shaft; a negative end surface slidingly contacting the cylinder block; and the other end surface slidably contacting the casing. a valve plate in contact with the valve plate, a pair of suction/exhaust ports that communicate with the cylinder intermittently are formed in the valve plate, and a suction/exhaust passage that constantly communicates with each of the suction/exhaust ports is formed in the casing. In the oblique shaft type hydraulic rotating machine, a support pin is provided in the casing on the tilting center of the cylinder block, the support pin and the valve plate are connected by a support member, and the support pin and the valve plate are connected to each other by a support member. An oil chamber is formed in the connecting portion to apply pressure in a direction to press the valve plate toward the casing, and an oil passage is formed in the valve plate to communicate the oil chamber with a high-pressure side port of the suction and discharge ports. A diagonal shaft type hydraulic rotating machine that is characterized by:
