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 on the cylinder block and has a plurality of cylinder holes parallel to the tilted axis and opened toward the torque plate; and a cylinder block that is slidably fitted into each cylinder hole of the cylinder block and has a substantially spherical shape. A plurality of pistons whose ends on the side opposite to the cylinder block are rotatably fitted into seats provided on the torque plate, and a spherical shape of each piston is attached to the surface of the torque plate on the cylinder block side. a piston retainer that slides in contact with an end of the piston retainer to prevent the end from coming off the torque plate; A piston pump or a motor comprising a valve surface having a connection port for connecting to a cylinder hole, and a synchronization mechanism for synchronizing rotation of the cylinder block and the torque plate, the piston retainer A piston pump or motor, characterized in that at least a portion of the piston that comes into sliding contact with the piston is made of an elastic member such as rubber.
