Claims

[Scope of utility model registration request]

A casing having an inlet/outlet port, an input/output rotating shaft supported by the casing, a torque plate rotatably provided on the rotating shaft, and an inclined axis that intersects with the rotation center of the torque plate. a cylinder block that is rotatably provided in the cylinder block and has a plurality of cylinder holes parallel to the tilted axis and opened toward the torque plate; A plurality of pistons are pivotally supported on a torque plate, and a connection port is provided in a casing to be attached to an end surface of the cylinder block on the opposite side of the torque plate for connecting the inflow/outflow port and each cylinder hole. A piston pump or a motor comprising a valve surface formed by a cylinder block and a synchronization mechanism for synchronizing the rotations of the cylinder block and the torque plate, the synchronization mechanism being provided so as to be rotatable integrally with the rotation shaft. A synchronizing rotary body, a spherical part formed on the outer periphery of the rotary body and having a spherical center aligned with the point where the rotation center intersects the inclined axis, and a narrow width protruding from a part of the spherical part. a cylindrical body extending from the inner periphery of the tip of the cylinder block; and an inward tooth that is disposed at the tip of the cylindrical body and is in sliding contact with the spherical surface and can mesh with the outward tooth. A piston pump or motor comprising:
