Abstract
A piston-cylinder unit includes a cylinder in which a piston rod is located so that the piston rod can move axially. A first connection mechanism is connected to the cylinder, and a second connection mechanism is connected to the piston rod. A positioning cylinder, with a pressure medium connection, is effectively connected to one of the first and second connection mechanisms. The distance between the first and second connection mechanisms can be set by the addition or discharge of pressure medium to or from the positioning cylinder. The positioning cylinder is located in series with the cylinder, and the piston rod forms a guide path or track for the positioning cylinder.
