Claims

[Claim for Utility Model Registration] The cylinder chamber and the gas tank are communicated through a gas inflow passage and a gas outflow passage, and the gas outflow passage is equipped with a self-pressure valve that opens when the gas pressure in the cylinder chamber increases. There is a spout at the bottom of the piston that is longer than the entire length of the cylinder chamber.
a notch is provided on the outer periphery of the tip of the spool, and the tip is inserted into the insertion hole provided in the lower part of the spool,
A gas cushion and a cylinder, characterized in that the insertion hole and the gas inflow path intersect at the position of the notch at the top dead center of the piston. ,
