ABSTRACT:
Hydraulically damping elastic bearing, in particular engine mounts for motor vehicles, with two rigid end walls opposite one another in the axial direction and at least two chambers containing damping fluid arranged axially one behind the other, whereby the chambers are connected for fluid communications with one another by a passage running in an annular fashion. For the variable modification of the length of the passage, partitions are inserted in the component containing the passage, which partitions divide the passage into individual passage segments connected for fluid communication with one another by an opening.
