ABSTRACT:
An annular piston abuts on an end face of a rotation plate on a side remote from a hollow cylinder via a thrust bearing, and delivery pressure is introduced to an end face of an annular piston on a side remote from the rotation plate via a high pressure-introducing passage. The delivery pressure acts via the thrust bearing on the rotation plate to urge the rotation plate toward the cylinder. As a result, the gap between the rotation plate and the cylinder is reduced, while a friction resistance offered to the rotation plate is reduced, thereby permitting the smooth rotation of the rotation plate.
