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.
