ABSTRACT:
A resilient bearing includes a cushioning member comprising an inner part, an annular element of a resilient material, and an outer part or shell, and a hydraulic damper having an inner space filled with a liquid and being divided by a partition into a working space and an equalizing space. The partition is provided with throttling passages for the liquid flowing therethrough, and the volumes of the separated spaces are variable. The hydraulic damper is accommodated in a housing which is independent of the cushioning member, and comprises a piston which is movable up and down in the working space, thereby varying the volume of the space, and is connected, directly or indirectly, to the inner part of the cushioning member.
