Abstract

Hydraulically damping motor bearing, elastic bearing, etc., with at least two chambers containing damping fluid and located axially one behind the other, at least one of which exhibits a wall designed as an elastic spring element, whereby the chambers are separated from one another by a partition and are connected with one another by means of a passage. To achieve a passage which is of simple design and easy to construct, the wall of the passage is formed partly by an elastic portion and partly by a rigid portion of the partition, and both the rigid portion and the elastic portion have a discharge opening emptying into a chamber.
