Beschreibung
Zusammenfassung:	A piston-cylinder unit for a hydropneumatic suspension system of a vehicle having a fluid-filled cylinder in which a piston having damping valves and connected to a piston rod is axially movable. The piston rod runs axially in a piston rod guide at the piston-rod exit of the cylinder and is sealed toward the outside by means of a piston rod seal. A spring surrounding the piston rod is in mounted between a first support part attached to the cylinder and a second support part attached to either the piston rod or a vehicle-fixed part. The spring, which interacts with an axially adjustable support part, can be lifted off one of the support parts. During compression of the piston-cylinder unit, the first and second support parts begin compression of the spring at the functional point of the compression. The functional point is adjustable in a predetermined position range by an adjustment device.
