Claims

[Scope of utility model registration request]

A rotating shaft supported by the casing via a bearing, a torque plate rotatable integrally with the rotating shaft, and a torque plate rotatable about an inclined axis intersecting the rotation center of the torque plate and parallel to the inclined axis. a cylinder block having a plurality of cylinder holes opened toward the torque plate; and a cylinder block that is slidably fitted into each cylinder hole of the cylinder block, and whose outer end is pivotally supported on a seat provided on the torque plate. A piston pump or motor, comprising a plurality of pistons, the torque plate and the cylinder block are configured to rotate synchronously and increase or decrease the volume of a pump chamber formed at the inner end of each piston. The torque plate is provided with an engaging recess as a synchronizing mechanism for synchronously rotating the torque plate and the cylinder block, and the cylinder block is provided with an arm that engages with the recess and slides within the recess, and the piston is rotated. A pressure pocket for pressure balance is formed in the pivoting seat to push the piston toward the cylinder block, and oil is guided from this pressure pocket to the sliding portion between the inner surface of the engagement recess of the synchronization mechanism and the arm. A piston pump or motor characterized by having a through hole.
