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; The valve surface includes a plurality of pistons whose outer ends on the block side are pivotally supported on the torque plate, and a valve surface having a connection port for connecting the inflow/outflow port of the casing and each of the cylinder holes. A piston-type pump or motor consisting of a piston-type pump or motor, in which a tilting plate is disposed on the anti-torque plate side of the cylinder block so as to be tiltable with respect to the torque plate, and the cylinder block can be freely and integrally rotated relative to the tilting plate. In addition to sliding together in a tiltable manner, an arcuate surface is formed on the back surface of this tilting board, and a tooth profile is carved along the arcuate surface. A variable capacity hydraulic engine characterized by having a rack or pinion that reciprocates or rotates.
