Abstract
A vibration damper with a hydraulic connection includes a check valve and a venting valve. The check valve and the venting valve can be actuated separately, and a hydraulic communication between the vibration damper and a connection opening of the hydraulic connection is switchable via the check valve. The venting valve is hydraulically connected in parallel with the check valve, and the hydraulic connection has a filling connection which is outfitted with the venting valve. The filling connection is opened independent from the position of the check valve and is closed by the venting valve.
