Abstract

A hydromount that is suitable for mounting a motor vehicle engine at a vehicle body includes a supporting spring supporting a mount core and surrounding a working chamber, and a compensating chamber separated from the working chamber by a separating assembly and delimited by a compensating diaphragm. The separating assembly may have at least two nozzle systems which have one decoupling diaphragm each and in each of which one damping duct is disposed. The compensating chamber and the working chamber may be filled with a liquid and may be connected to each other in a liquid-conducting manner by damping ducts. The separating assembly may have an absorber duct connecting the working chamber with the compensating chamber. A switchable actuating member may be assigned to the absorber duct.
