Abstract
A hydraulic drive cylinder with a cylinder tube, which at its respective ends has a cylinder base and a cylinder head, thus delimiting a cylinder space. A piston can move to and fro in the cylinder space between the cylinder base and the cylinder head, which piston delimits a head-side chamber and a base-side chamber, which chambers are sealed off from one another by the piston. The piston rod has a free end which is delimited by an end face, which end face is situated in the head-side chamber. At the said free end, the piston rod is provided with a first stop. The piston is provided with a projection which extends towards the cylinder head inside the head-side chamber and is provided, at a distance from the piston, with a second stop, in such a manner that the piston rod can move to and fro along an axial travel with respect to the piston, between a retracted position with respect to the piston and an extended position with respect to the piston, in which the first and second stops bear against one another, and in such a manner that when hydraulic pressure is present in the head-side chamber the piston rod adopts the extended position with respect to the piston.
