ABSTRACT:
A hydraulically damped mounting device has a first anchor part in the form of a tube and a second anchor part in the form of a ring around the tube, which ring is connected to the tube by a resilient wall. The device has a working chamber for hydraulic fluid partially bonded by the resilient wall and connected to a compensation chamber by a passageway. The chamber is partially bounded by a flexible bellows which may have a ribbed surface. The first anchor part may also include a helmet extending over the flexible bellows, which helmet is in abutting non-bonded contact with the tube. The second anchor part may have components forming a support arc to which the resilient wall is attached and a radially inner positioning arc.
