<p>PURPOSE:To prevent a pressure drop in a fluid chamber by providing a check valve which loads on a vortex chamber body so that an elastic plate is pressed to close one opening of the valve body. CONSTITUTION:A valve body 14 divides an inner tube 11 into two upper and lower fluid chambers 10, 11. Openings 15, 16 are formed in the upper wall and the lower end of the valve body 14, communicating with the upper fluid chamber 10 and the lower fluid chamber 11, respectively. A few ring-like elastic plates 17 are supported by a snap ring 18 which is stuck into an internal periphery of the chamber 11 in the vicinity to the opening 16. A columnar vortex chamber body 19 is freely movable to be contained inside the valve body 14 between the elastic plates 17 and the upper wall and a spring 24 loads on the vortex chamber body 19 against the elastic plates 17 which are disposed at the lower opening 16 of the valve body 14, to close the opening 16.</p> |
