Abstract
In a hydraulically damped resilient mounting of the type where an elastomeric spring 2 and a diaphragm 4 define two liquid-filled chamber 8, 9 which communicate via a throttle 17, a chamber 10 on the other side of the diaphragm (which would normally be at atmospheric pressure) can be subjected to a reduced pressure when desired. This causes the diaphragm 4 to deflect to the dotted line position which induces cavitation in the liquid. This renders the throttle 17 and therefore the hydraulic damper ineffective, thus removing a source of undesirable noise. When the mounting is used to mount a vehicle engine, vacuum is supplied from the manifold either selectively or automatically in response to sensed parameters. <IMAGE>
