ABSTRACT:
A resilient mounting, such as a rubber mounting, with hydraulic damping, in particular for mounting engines of motor vehicles, has two rigid end walls which are disposed opposite to each other in the axial direction, and at least two chambers which are disposed axially one behind the other and which contain damping fluid. The chambers are separated by a rigid partitioning wall. The chambers communicate with each other through a flow passage which extends in an annular configuration around the axis of the mounting, the flow passage being formed in the rigid partitioning wall. The rigid partitioning wall is arranged radially inwardly of, and supported by, an elastic, axially movable diaphragm which is fixedly and sealingly clamped at its outer periphery. At least one of the chambers is defined in part by a rubber-elastic spring member constituting part of the generally peripheral wall of the chamber. Travel-limiting surfaces may be provided at the periphery of the rigid partitioning wall, outboard of its connection to the diaphragm, so as to control movement of the rigid partitioning wall.
