Abstract

A hydraulically damped engine mount includes two separate working chambers 1 which are filled with liquid and are at least in a partial area bounded by a resilient wall 2 and joined by a damping opening 4. At least one of the working chamber 1 is additionally joined to a compensating chamber 3 by means of a compensating opening 5. By means of a flexible and substantially nonelastic wall 4a, the compensating chamber 3 is suited for the pressureless reception of additional liquid. The compensating opening 5 exhibits a flow resistance which is substantially greater than that of the damping opening 4.
