Claims

[Scope of utility model registration request]

a cylinder, a first piston slidably disposed within the cylinder having a first port for fluid flow during extension and a second port for fluid fluid flow during retraction; a piston rod that is connected to the piston and has an upper end projecting outward from the cylinder, and has a gas chamber provided therein, a hole that is opened in the axial direction from the lower end and communicates with the gas chamber, and a piston rod that has an upper end that projects outward from the cylinder; a first piston rod having a communicating passage; a second piston rod fixed to the bottom of the cylinder and extending through the hole into the gas chamber; and an upper end of the second piston rod. a second piston fixed to the front gas chamber below a portion where the passage opens; and a second piston fixed to the first piston rod below the first piston and communicating with the passage. a first valve body that opens and closes a lower end of the first port; a first compression coil spring disposed between the valve body and the first bellows; a second bellows fixed to the first piston rod above the piston and communicating with the passage; a second valve body that opens and closes the upper end of the second port; a second compression coil spring disposed between the bellows;
Hydraulic buffer.
