Abstract
PURPOSE: To provide a fluid rotation machine for fluid motors, fluid pumps and the like which enables the reduction in noise with fluid pressure in a pressure chamber such as cylinder chamber so arranged to be almost balanced with that of a port successively communicated beforehand.
CONSTITUTION: As a cylinder block 3 rotates, a piston 8 revolves along an inclined surface of a swash plate 9 to cause a change in the volume of the respective cylinder chambers according to the degree of inclination whereby compressed high pressure fluid is delivered via a delivery port 16. In a fluid rotation machine of such an arrangement, an orifice 19 is provided cut on a valve plate 11 at a position where the right end of a cylinder port 6 is communicated to the orifice immediately after the left end thereof gets off a suction port 13, while it is communicated to a chamber 20 formed in a housing 1 independently isolated from the delivery port 14. In other words, the cylinder changer 7 is communicated to the chamber 20 at a bottom dead point X immediately before entering the delivery process
