ABSTRACT A resilient bearing (1;35) for damping oscillations of equipment, in particular vehicle engines, avoids resonance step- ups at approximately 12 Hz. In this bearing, damping fluid is pumped from a working chamber (22) over spherical flow surfaces of suitable surface configurations (30 - 32) or flow resistance of a membrane (50) into an equalizer chamber (23). Operating noise is avoided by decoupled support of the partition and by free travel of the membrane (16; 41; 50). In order to prevent dynamic stiff- ening at higher frequencies the equalizing chamber (23) with an integrated choke system is additionally elastically supported in the bearing housing (4).
