Abstract
A hydraulic-damping engine mount includes a working chamber having a given diameter and a compensating chamber. A rigid intermediate plate is disposed between the chambers. A conical jacket-like rubber-elastic wall has relatively smaller and larger diameter ends. A metal bearing plate is disposed at the smaller diameter end and at least partly defines the working chamber along with the intermediate plate and the wall. The intermediate plate has an overflow opening formed therein interconnecting the chambers. A rigid plate in the form of a circular disk has a diameter smaller than the given diameter. The rigid plate is disposed in the working chamber parallel to the intermediate plate and is rigidly connected to the bearing plate.
