Abstract

The cylinder consists of a double-wall cylinder tube (1) with flow grooves, a guide part (2), a bottom closing part (3) and a piston rod (6) with piston (7) between a piston cavity (31) and an annular piston cavity (32). The bottom closing part contains a control cylinder cavity (8) with a control piston (15) kept in the blocking middle position by springs (13, 14) on either side.The unpressurized fluid in the piston cavities blocks the movement of the piston and its rod. When pressure is applied, the system is unblocked.
