Abstract: Hydraulically damping rubber bearing, consisting of an inner tube, an outer tube located concentrically or eccentrically in relation to the inner tube and at some distance from it, and a rubber part inserted between them in which there are at least two chambers which are filled with damping fluid and are hydraulically connected to one another, whereby in each of at least two chambers there are respective stop bodies, whereby the stop bodies are connected to one another by means of an element which has a hydraulic connection, the element thereby has a groove which is open toward the radial outside and is located on the inside of the outer tube so that the groove, together with the inside of the outer tube, forms the flow connection, whereby the element is realized in one piece, and whereby the element has an opening over its axial length, the clear width of which opening is larger than the diameter of the inner tube.

Abstract: A hydraulically damping elastic bearing comprises an inner tube, an outer tube concentric or eccentric in relation to and located at some distance from the inner tube. An elastic part is inserted between them to include at least two chambers filled with damping medium. The two chambers are connected to one another by a flow connnection. To prevent cavitation and/or the formation of gas bubbles in the damping fluid, and to prevent a possible underpressure in a chamber when the chambers are not symmetrical, the damping medium is pressurized with an overpressure which is above atmospheric pressure.
