Claims

[Scope of utility model registration request]

The piston rod inserted into the cylinder body has a fixed piston and a fluid chamber within which the fixed piston can slide back and forth for a predetermined stroke, and itself can slide back and forth for a predetermined stroke in the fluid chamber inside the cylinder body. In addition to providing a free piston, the cylinder body is provided with pressurized fluid supply and discharge ports that open to the forward side chamber and the backward side chamber of the fluid chamber, and the piston rod is provided with pressure fluid supply and discharge ports that open to the forward side chamber and the backward side chamber of the fluid chamber, and the piston rod is provided with a A two-stage stroke that has an internal flow path leading from the side chamber to the outside of the cylinder, and further has a communication path in the free piston that allows communication between the backward movement side chamber of the fluid chamber and the forward movement side chamber of the fluid chamber in the cylinder body. type fluid pressure cylinder.
