Zusammenfassung:A vibration damper for a vehicle may include an outer tube, a middle tube, and an inner tube arranged coaxially. The inner tube is at least partially filled with damping medium, and a piston rod is arranged in the inner tube so as to be movable to and fro. A working piston arranged on the piston rod is movable with the piston rod. An inner chamber of the inner tube is divided by the working piston into a rod-side working chamber and a rod-remote working chamber, with a connecting element being arranged between the inner tube and the middle tube on each side of a middle tube opening facing tube ends of the middle tube. The connecting element may include a radially circumferential sealing element that seals a middle tube balancing chamber against an outer tube balancing chamber at least with respect to the damping medium.
