Elastically yieldable mount, in particular for the suspension of a vehicle engine

In this mount, the two liquid-containing chambers (15, 16) are separated by a single-piece member (10) of elastomer which comprises a central movable portion (13) connected to a massive peripheral portion (11) by a thin web (12) in the form of a circular wave. Defined between the periphery of the peripheral portion (11) and the end elements (4, 7) of the mount is a circular passageway (19) which has an extent of more than a turn and connects the two chambers to each other. This mount is easy to construct and ensures both a good filtering of high-frequency and small amplitude vibrations due to imperfections in the balancing of the engine and a good damping of low-frequency and large amplitude trembling coming from the road.
