Abstract
A hydraulically damped rubber mounting in which a liquid filled working chamber 1 is bounded in at least a first partial area by a plate 3 which is made of a magnetizable material and supported on a spring 2. Depending upon the parameters, the plate 3 can be moved back and forth in direction of the working chamber 1 by means of a magnetic system. The transmission of acoustically effective vibrations via the rubber mounting can thus be suppressed.
