Abstract:
A fluid pressure cylinder is provided with a piston rod, a cushion chamber that decreases in volume as the fluid pressure cylinder extends, a communication channel for communicating the cushion chamber and a rod-internal chamber, a throttle passage that exhibits a cushion function by applying resistance to the flow of a working fluid from the cushion chamber to the rod-internal chamber, a check valve provided to a piston and having a check function for communicating the rod-internal chamber and a drive chamber and allowing the working fluid to flow only from the rod-internal chamber to the drive chamber, and a pilot passage formed in the piston and dispelling the check function by guiding the pressure of the cushion chamber as pilot pressure to the check valve.
