Claims

[Scope of utility model registration request]

One end of a large-diameter main cylinder with both ends closed is connected to one end of a small-diameter sub-cylinder concentric with the main cylinder, and a main piston and a sub-piston are inserted into the main cylinder and the sub-cylinder so that they can reciprocate, respectively. A rod having a cross-sectional area equal to the cross-sectional area of the sub-cylinder is connected to each end surface of the piston, and one rod passes through one end of the sub-cylinder in an oil-tight manner and is connected to the main piston.
The other rod penetrates the other end of the sub-cylinder in an oil-tight manner and extends outward from the sub-cylinder, and the main piston has a valve mechanism that allows oil to flow in the opposite direction to the direction of movement of the main piston. One end of the main cylinder and the other end of the sub-cylinder are connected by a pipe having the same cross-sectional area as the rod, and the pipe is provided with a variable orifice. absorber.
