ABSTRACT:
A shock-absorbing resilient support for the suspension of a body on a support structure, particularly for the suspension of motor vehicle engines, motor lorry cabs and the like, comprises a chamber having a variable volume, which is filled with gas under pressure and serves to support at least part of the weight of the suspended body. The support further comprises two variable volume chambers filled with a viscous fluid and separated by a dividing wall provided with at least one passage for the transfer of viscous fluid from one chamber to the other upon displacement of the suspended body with respect to the support structure. Valve means are provided to vary the overall flow cross-section which puts the two chambers filled with the viscous fluid into communication with one another in the event of low frequency, high amplitude displacements of the suspended body with respect to the support structure. In one particular embodiment, the damping effect can be different according to whether the suspended body is displaced upwards or downwards.
