ピストン型流体機械。 A plurality of cylinders and a valve plate, which are arranged at predetermined intervals in the circumferential direction within a cylindrical surface centered on the rotation axis, are fitted into the cylinder by relatively rotating them around the rotation axis. The installed piston is reciprocated in the axial direction, and the cylinder chamber limited by the cylinder and piston is alternately connected to a cocoon-shaped high pressure port and a low pressure port that open to the end face of the valve plate through the cylinder port. In the axial piston type fluid machine, one or more small holes communicating with the high-pressure port or the low-pressure port are inclined in the circumferential direction and opened at the end face of the valve plate on the starting end side of the high-pressure port or the low-pressure port. An axial piston type fluid machine featuring:
