ABSTRACT:
A hydraulic-damping engine mount includes a working chamber, a frustoconical elastomeric support spring surrounding the working chamber, a compensating chamber, and a soft-elastic cup-shaped diaphragm bordering the compensating chamber. A partition is disposed between the chambers. The circular-annular overflow conduit through which the chambers hydraulically communicate with each another has a substantially rectangular cross section and is in the vicinity of the partition. At least one rib-like intermediate wall inside the overflow conduit extends in the circumferential direction and extends vertically over a portion of the height of the overflow conduit.
