Abstract
Hydraulically damping elastic bearing with two rigid end walls opposite one another in the axial direction, and at least two chambers located one behind the other and containing damping fluid, at least one of which has a circumferential wall designed as an elastic spring element, whereby the chambers are separated from one another by a partition which is at least partly elastic exhibiting slits for an exchange of fluids. The elastic partition should thereby be designed so that when there is flow against the membrane from different chambers at the same pressure, a different pressure reduction is possible. For this purpose, the elastic partition is asymmetrical in cross section in relation to its center line, at least in the area of the slits, so that the opposite surfaces of the elastic partition are at different distances from the center plane in the area of a slit.
