Abstract
A two-chamber engine mount with hydraulic damping has a partition arranged between a working space and an equalization space. The partition is formed in a first subarea by a disc movable between stops. The play of the disc between the stops can be varied by a motor. In a second subarea, the partition is penetrated by a first choke canal. A second choke canal can be added to the first choke canal in series or parallel therewith by a motor.
