Abstract
The hydraulic antivibration support has two rigid strength members interconnected by an elastomer body that has a thick bell-shaped wall, said wall defining a liquid-filled working chamber communicating with a compensation chamber via a narrow channel. The thick wall is of rectangular section and the elastomer body further includes a projection extending in the center of said wall and presenting four side faces each facing one of the sides of said thick wall. Two opposite side faces of the projection are concave in shape so that the projection has a narrow central portion between two thicker end portions.
