<p>A sealing ring (29) is provided between a end plate (26A) of an eccentric rotation body (21) and a support plate (17) so that the pressure of fluid at high pressure is allowed to work on the end plate (26A), thereby allowing axial-direction pressing force to work on the end plate (26A). The sealing ring (29) is arranged eccentrically away from the center of a cylinder (21) as the eccentric rotation body (21) to minimize separation of the axial-direction pressing force from a thrust load in the radial direction in the end plate (26A) of the eccentric rotation body (21), thereby reducing turnover moment effectively.</p> |
