Abstract

A shock-absorbing mounting (for example, for supporting a vehicle engine on the vehicle chassis), comprises a tubular supporting body 10 which is connected by an annular element 16 of elastomer material to a coupling member 22. The tubular body 10 is closed off by a transverse wall 34 to define a liquid filled chamber 40. A piston-like plate element 32 connected to the coupling member 22 divides the chamber 40 into two-subchambers 40a, 40b which communicate around the periphery of the plate element 32. Large amplitude low frequency oscillations of tie coupling member 22 cause fluid to be forced between the sub-chambers (40a, 40b) to produce a fluid damping effect. At least a part of the chamber wall is resiliently yieldable to enable the absorption of small amplitude high frequency oscillations without any fluid damping being produced. Instead of the transverse wall 34 being made resilient, the elastomeric element may be made with thinner portions so that it can yield.
