The rubber body forms at least two chambers (5, 6) are formed, which are filled with damping medium and permanently communicate with each other. An elastically deformable body forms a protective tube (4), into which the inner and outer mounting sleeves (2) are sealingly inserted. An overflow channel (8) with a shut-off device, which opens automatically at a predetermined pressure differential in the two chambers (5, 6) by radial deformation of the protective tube (4), is provided between the chambers (5, 6).
