ABSTRACT:
A hydraulically dampening bearing which has an internal tube, an external tube and a rubber, or elastomeric, spring inserted between them. Chambers containing dampening fluid are hydraulically connected with one another via throttled passages. An equalizing chamber is connected to at least one of the chambers by a connecting line. The equalizing chamber is subdivided by an equalizing membrane into a first subchamber with dampening fluid and a second subchamber which receives a fluid pressure from an external source.
