ABSTRACT:
A hydraulic antivibration support comprises first and second rigid strength members, an elastomer body having a thick wall interconnecting the two rigid strength members and defining a hydraulic working chamber, and a thin wall defining a hydraulic compensation chamber which is connected to the working chamber via a narrow channel. The elastomer body is extended by a flexible elastomer tongue which is received in a slot-shaped housing of the second strength member, said housing including a face in communication with the working chamber and a face in communication with the compensation chamber, both faces being closable in alternation by the flexible tongue.
