PROBLEM TO BE SOLVED: To enable a compression mechanism for supplying high-pressure lubricant in a stationary side oil groove to a movable side oil groove to reliably supply the high-pressure lubricant to a fluid chamber.SOLUTION: The compression mechanism is configured to perform a first movement where only the stationary side oil groove 80 and the movable side oil groove 83 are communicated to each other out of the stationary side oil groove 80, the movable side oil groove 83 and the fluid chamber S and a second movement where the movable side oil groove 83 is communicated to both of the stationary side oil groove 80 and the fluid chamber S one another simultaneously after the first movement.SELECTED DRAWING: Figure 7 |
