ABSTRACT:
A vibration isolation mount for elastic suspension of an automobile engine having a body containing a dampening liquid controlled so as to maximize the dampening of low frequency oscillations having a high amplitude and to minimize high frequency oscillations having a small amplitude. The flow of dampening liquid between two chambers is controlled by a pair of bell-shaped elements nested together to form a conduit therebetween. The bell-shaped elements can be rotated with respect to each other, preferably by an electric motor, to open and close perforations in the bell-shaped elements.
