Abstract
A telescopic vibration damper, comprising a pressure tube filled with a damping medium, in which a piston rod is arranged such that it can move axially, the pressure tube being axially displaceably guided in an intermediate tube. An annular chamber between the pressure tube and the intermediate tube is likewise filled with the damping medium, there being a flow connection between the pressure tube and the annular chamber, and a compensating chamber accommodates the displaced volume of the components that can be telescoped toward one another. The annular chamber formed by the intermediate tube and the pressure tube, and the pressure tube, are hydraulically separated from the compensating chamber.
