Abstract

The invention relates to a hydraulic cylinder comprising a piston rod (70) bearing at least one tool receiving element (120). Said hydraulic cylinder is characterised by an automatic disconnection device which is controlled in a hydraulic-mechanical manner, with a medium for the actuation of the hydraulic cylinder. Said medium which is used for building-up force, is also the medium which is used for the automatic disconnection device. Said hydraulic cylinder also comprises a first valve slider (100) and a second valve slider (140) which are used for disconnecting the displacement of a piston (40), which is connected to a piston rod (70), according to a possible obstruction found in the path of the outward moving piston rod (70) before a desired position by deviating the medium in the region of the piston (40).
