ABSTRACT:
A piston cylinder assembly which includes a work cylinder, a piston and a piston rod, which piston rod carries the piston and extends out of the work cylinder in a sealed manner, as well as a ring-shaped equalization chamber formed by two tubes is disclosed. The equalization chamber is divided by a separating piston into two partial chambers, the separating piston having two parts which are guided so that they can move in a sealed manner axially on the wall of the respective tube of the compensation chamber facing the respective part. The two parts of the separating piston are connected by a flexible portion allowing them to move radially with respect to one another and are sealed with respect to one another.
