Abstract

PURPOSE: To enable the work in response to an action order to be completed in several miliseconds to tens miliseconds after the order has been given, by using a poppet type valve which moves forward and backward a piston.
CONSTITUTION: After an action order has been given, an operating rod 54 is pushed by a solenoid and the like, and a back pressure part of a check valve 49 is connected with a passage 52. This causes the check valve 49 to be pushed upward. Then a pressured oil from an accumulator flows into a chamber 31 through a hole 48, and pushes upward a piston 28 and a poppet valve 19. And thus, the pressured oil working on the inside of a chamber 13 flows into a chamber 15, and flows into a chamber 10 after having opened a check valve 14. This causes a piston 2 to be driven at a high speed due to a difference in an area between a left side and a right side.
