Abstract (en)

[origin: EP0961037A1] The piston (1) is positively locked in a cylinder (3) at stroke end, by locking elements (4). For each end position, there are locking elements, a pretensioned locking piston (6), and a locking element carrier (7), which are all positioned within the ring chamber between piston rod (2) and cylinder. The locking elements are not spherical. The space for the tension spring (5) for the locking piston is relieved to the opposite working chamber via a channel (12) and a valve (13). All required components are of modular construction.
