Claims

[Claims for Utility Model Registration] (1) A cylinder, a cylinder located within the cylinder,
a piston rod with one end protruding outside the cylinder, a fixed piston provided on the piston rod, and a fluid sealed within the cylinder;
The buffer includes a floating piston that is movably positioned in the cylinder in the axial direction of the cylinder independently of the fixed piston and absorbs changes in the volume of the fluid, the buffer being configured to prevent the piston rod from returning. is carried out by the elastic force of the gas sealed between the floating piston and the closed end of the cylinder,
A shock absorber characterized in that the closed end of the cylinder is provided with a check valve mechanism that allows gas to pass only in a direction from the outside into the cylinder. (2) The shock absorber according to claim 1, wherein the check valve mechanism provided at the closed end of the cylinder is connected to a variable pressure gas pressure source. (3) The shock absorber according to claim 1 of the utility model registration, characterized in that the gas is air.
