Abstract
The invention relates to an arrangement for a fluid-driven lock cylinder for the actuation of moving parts such as slides, cores and corresponding units on press tools and injection moulding tools for metal or plastic materials. A piston is accommodated in a displaceable fashion in a piston cylinder. A divided ring forms an end stop for the piston. The stop ring exhibits a maximum diameter which exceeds the diameter of the piston. An inclined external axial part of the stop ring forms a stop for making contact with a counter-pressure part of the piston cylinder. The counter-pressure part is inclined to a degree corresponding to the inclination of the end stop on the stop ring.
