ABSTRACT:
A hydraulically acting damping element includes a main chamber and a compensation chamber. Two rigid end walls and a rubber-elastic circumferential wall surround one of the chambers. An elastic, pressure-stable bellows has ends and a circumference. The bellows is disposed concentrically inside the one chamber and rigidly joined to the end walls with the main chamber inside the bellows and the compensation chamber between the bellows and the circumferential wall. An over-flow circuit is formed on one of the ends of the bellows and extends over at least part of the circumference of the bellows for hydraulically connecting the main chamber and the compensation chamber.
