Abstract

An adjustable vibration damper includes at least one adjustable damping valve, with a piston at a piston rod that divides a cylinder into a work chamber on the piston rod side and a work chamber on the side remote of the piston rod. The cylinder is at least partially enclosed by an intermediate tube that forms a fluid connection between one of the work chambers and the adjustable damping valve. A hydraulic apparatus is connected to the fluid connection of the one work chamber via a first line and to the other work chamber via a second line.
