Abstract
It relates to a hydraulic antivibration support interposed between a chassis and a vehicle engine, comprising a working chamber A and a compensation chamber B filled with liquid and joined together by a throttled passage (6) constituted by a "column" in a circular arc hollowed in the annular seat (5.sub.2) of a central deformable partition (5.sub.1). To increase the number of oscillatory phenomena which can be damped in excellent manner by the "column" effect, there is provided at least one small hole (8) joining one of the chambers A to a point of the throttled passage (6).
