Abstract
The invention relates to a hydraulic antivibratory device comprising a rigid core, a rigid circular base and an annular supporting elastic wall sealingly connecting the core to the base, the inner space of the box so formed being filled with liquid L and the core being extended inside the box, by a rigid foot itself terminated by a piston whose contour defines, with the opposite wall portion a throttled annular passage for the liquid. The base is perforated by at least one port whose length is very much less than the mean diameter and the base, external to the box is capped by a flexible and sealed bellows adapted to form with it a pocket of variable volume.
