Title: Damping stopper
Inventor: FUJITA TOSHIJI
IPC: F16F9/346
Filed: 1992-12-08
Abstract: PURPOSE:To reduce a shock when a moving body is stopped by providing a fluid controller for communicating fluid spaces partitioned by a cylinder and a piston with each other and varying fluid moving easiness according to a moving position of the piston, a flow passage and a check valve in the piston. CONSTITUTION:If a load is not applied to a receiving portion 33 of a shaft 9, a piston 5 is moved leftward by a coil spring 19. Since a check valve 23 is not conducting an inhibiting function, oil in a fluid chamber B flows into a fluid chamber A through a flow passage 21 of the piston 5. As a result the piston 5 is moved in a short time. When a moving body collides against the receiving portion 33, the piston 5 is moved rightward. Accordingly, a pressure of the oil in the fluid chamber A is increased so that the check valve 23 is closed, and the oil flows into the fluid chamber B through pipelines 29 and a common pipeline 31. A quantity of the oil flowing in the pipelines 29 is adjusted by flow rate adjusting valves 27. Oil flow easiness is decreased by the moving piston 5 closing communication hoes 25 of a cylinder 3 in sequence, so that the piston 5 is decelerated gradually into a halt. Consequently, a chock to be applied to the moving body can be reduced.
