ABSTRACT:
A hydraulically damped mounting device has two anchor parts connected by a resilient wall which applies a spring force to relative vibrations of the anchor parts. Also connected to the anchor parts are two bellows walls each defining a corresponding chamber for hydraulic fluid, which chambers are interconnected by a passageway. The bellows walls deform substantially freely of spring resistance and so the volume of the corresponding chamber can change without spring resistance. Thus there is a pumping action of fluid between the chambers, giving a damping action due to the passageway, and hence the spring and damping characteristics of the mount are independently selectable.
