Abstract
PURPOSE:To prevent high surge pressure from occurring in an actuator by arranging cushioning conduit groups to be blocked gradually in steps as an oscillating body oscillates in the direction for approaching the side of a fixed shoe. CONSTITUTION:Cushioning conduit groups 3A, 5B opening in pressure chambers 10A, 10B held between main conduits 2A, 2B and throttle conduits 6A, 6B are formed in a casing 7. The cushioning conduit groups 3A, 5B are so arranged to be blocked gradually in steps as an oscillating body 8 oscillates in the direction for approaching the side of a fixed shoe 9. Inasmuch as the passing area of the pressurized oil discharged to the side of (A) port in response to the dimishing diminution of oil quantity stored within the pressure chamber 10A, 10B is reduced in steps, and finally, the oscillating body 8 collides with the fixed shoe 9 at the speed corresponding to the opening degree of a throttle valve 6A. In this manner, a high surge pressure can be prevented from occurring at the moment when the main conduits 2A, 2B are blocked.
