Abstract
The invention relates to an antivibration support comprising, between two rigid elements, a box which defines two deformable chambers filled with liquid separated by a deformable partition and communicating with each other through a throttled passage. The partition is constituted by a diaphragm surrounded by a beading which is gripped between two perforated thin metal disks, the periphery of the first disk alone is overlapping and fixed to one of the rigid elements, and the passage comprises a curvilinear channel bounded by areas of the beading, of the first disk and of an elastic wall of the box.
