Vibration damper and middle pipe for vibration damper

The invention relates to a vibration damper and a middle pipe for a vibration damper. The vibration damper (1) for a vehicle may include an outer tube (2), a middle tube (3), and an inner tube (4) arranged coaxially. The inner tube is at least partially filled with damping medium, and a piston rod (9) is arranged in the inner tube so as to be movable to and fro. A working piston (10) 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 (11) and a rod-remote working chamber (12), with a connecting element (13) being arranged between the inner tube and the middle tube on each side of a middle tube opening (7) facing tube ends of the middle tube. The connecting element may include a radially circumferential sealing element (14) that seals a middle tube balancing chamber (60) against an outer tube balancing chamber at least with respect to the damping medium. 本发明涉及减振器和用于减震器的中管。一种用于车辆的减振器(1)包括：彼此同轴布置的外管(2)、至少一
