ABSTRACT:
A hydraulically damped resilient mounting having a housing that is closed off on opposite sides by resilient elastomeric elements to form an interior of the housing. A partition is disposed in the housing between the resilient elastomeric elements in such a way as to divide the interior of the housing into two chambers that are filled with damping fluid. The partition is provided with a flow passage so that the volumes of the two chambers can be reciprocally varied. The flow passage includes a hollow chamber that forms a large portion of the surface area of the partition. The flow passage also includes an at least nearly tangentially disposed inlet, in the outer peripheral region of a partition, to provide communication between one of the two chambers and the hollow chamber. The flow passage further includes an at least nearly axially disposed outlet, in the central portion of the partition, to provide communication between the hollow chamber and the other of the two chambers.
