Abstract:
A hydraulic vibration-damping support serving to interconnect two rigid elements for damping purposes, the support comprising at least:first and second rigid strength members serving to be fixed to respective ones of the two rigid elements to be interconnected; an elastomer body interconnecting the first and second strength members; a working chamber filled with liquid, and defined in part by the elastomer body; at least one easily-deformable compensation chamber; and a decoupling flap which comprises a flexible membrane that is mounted to move with clearance between first and second rigid gratings that communicate respectively with the working chamber and with the compensation chamber, the first and second gratings being carried respectively by first and second rigid support pieces fixed to the second strength member; wherein the first and second rigid gratings and the rigid support pieces together define a partition that separates the working chamber and the compensation chamber and wherein the first and second gratings are connected by elastic links to respective ones of the first and second support pieces.
