Abstract
A hydraulic-damping rubber mounting for motor vehicles, particularly for engines of such vehicles, has two rigid end walls which are disposed opposite to each other in the axial direction, and at least two fluid chambers which are disposed axially one behind the other, for containing damping fluid. The chambers communicate with each other through a throttle means. A partitioning wall which delimits and separates the two chambers is axially movable, and is pressed against a sealing surface by way of a prestressed rubber spring so that, at large amplitudes, the reduced pressure which normally might cause cavitation in a chamber is eliminated by way of a bypass opened by stressing the rubber spring so as to open communication at the sealing surface, such that no interfering noise effects occur.
