Abstract
In a hydraulically damped rubber bearing, a supported component is attached to a supporting component by an element made of resilient material. The supported and supporting components enclose an activating chamber occupied by a fluid. The activating chamber is separated from a compensation chamber by a partition. The partition accommodates at least one port. At least some of the partition is flexible. The compensation chamber is sealed off from outside by a diaphragm secured to the supporting component. The flexible section of the wall and the diaphragm are molded in one piece. The molding is fastened to the partition essentially fluid-tight in the zone between the flexible section and the diaphragm.
