Abstract

A two-chamber engine mount has a working space and a compensation space which are filled with liquid and connected by a choke aperture having the shape of a canal. The inlet and outlet openings of the choke canal are rigidly related to the choke canal and define its beginning and end. At a distance from the inlet opening of the choke canal, at least one transverse passage opening is provided parallel to the outlet opening. The transverse passage can be shut off by a valve which can be actuated by a signal.
