A support assembly especially suitable as a drive unit support includes a block of resilient material having inserts made of substantially harder material with facing surfaces which extend in nonparallel directions to at least partially extinguish sound waves of disturbing vibration frequencies by interference after reflection from the surfaces.

Resilient support assembly providing vibration suppression

In the embodiment described in the specification, a cushion bearing for motor vehicles has two rigid bearing seats with a resilient rubber bearing block and an air spring acting between the seats. The air spring has a bellows forming a chamber divided into two compartments by a throttling plate which is connected to one of the bearing seats by way of a central rod and a rigid housing connected to the other bearing seat encloses the bellows. The bellows has at least one intake valve so that the air spring is automatically pumped up during relative motion between the bearing seats.

In the representative sound-insulating engine mounts described in the specification, a resilient pad of elastomeric material is disposed between pan-shaped members having side walls which are spaced from the periphery of the resilient pad in the absence of dynamic loads so as to provide resilient stops for the pad deformation.

Mount with insulation for solid-conducted sound, in particular for an

An air intake pipe, for mounting to the air filter of an internal combustion engine has two air flow channels having different lengths. A duct is provided between the air flow channels connecting them over their entire length. The duct is dimensioned to provide both sound attenuation and acoustic wave interference between intake noises in the two channels. Thus, the intake pipe acts as an intake noise silencer.
