Abstract
A resilient mounting for engines, machine units, etc. During driving operation, resilient motor mounts having a supporting diaphragm-like element which oscillates freely via an air cushion generate undesirable and annoying noises, and they also transmit to the chassis and the body, in a practically undamped fashion, low-frequency oscillations. The present invention therefore provides an effective acoustic uncoupling, without adversely affecting the spring or shock absorption characteristic, via a damping device in the form of a flexible diaphragm which is provided with a throttled transfer hole. This diaphragm is attached between the air cushion and a supplemental space which receives compressed air, the pressure of which can be regulated.
