機械。A piston-type rotating system in which a piston is housed in a cylinder provided in a cylinder block that rotates within a casing, and fluid is supplied and discharged into the cylinder through suction and discharge ports provided in a valve plate that contacts the end face of the cylinder block. In the machine, an orifice for removing residual pressure fluid in the cylinder is provided in a valve plate portion between a discharge port and a suction port of the valve plate, and the orifice and the inside of the casing are larger in diameter than the orifice. A piston-type rotary fluid machine characterized by connection via a discharge passage on the casing side.
