Abstract
The invention relates to an antivibratory support to be fitted between the chassis and the engine of a vehicle, which support comprises two deformable chambers filled with liquid (12) and communicating with each other through a constricted passage (11), namely a work chamber (A) defined by a bowl (1) connected to the chassis, by a thick resilient ring (7), by an internal bell (8) connected to the engine and plunging into the bowl and by a dividing wall (10) closing this bell, and a compensation chamber (B) defined by the dividing wall and by a bellows (9) inside the bell. The bowl comprises a re-entrant flange (3) and the bell a peripheral bead (8.sub.1) covered with an annular rubber shoe (13), which cannot pass through the opening defined by said flange.
