ABSTRACT:
A hydraulic antivibration support comprises two rigid strength members interconnected by an elastomer body which defines a working hydraulic chamber communicating with a compensation chamber via a constricted passage. The two hydraulic chambers are separated by a rigid partition formed by two grids disposed side by side, and a decoupling valve member is clamped between the grids. The decoupling valve member comprises a deformable membrane that, in the rest position, is closer to the second grid than to the first grid.
