A hydraulic vibration-damping support comprising two strength members interconnected by an elastomer body defining in part a working chamber filled with liquid, said working chamber communicating via a constricted passage with a compensation chamber separated from said working chamber by a rigid partition. The constricted passage is made up of two stages defined by two pieces of sheet metal forming the rigid partition.

Hydraulic vibration-damping support

Anti-vibration support comprising two rigid armatures connected to each other by an elastomer body which has, on the one hand, a bell-shaped side wall and on the other hand, a central foot extending inside the side wall from the top of the elastomer body to a baseplate forming one of the armatures. The side wall has vertical reinforcement ribs which extend radially outwards and which are adapted to prevent the central foot from keeling over.

Anti-vibration support

An antivibration support has two rigid strength members interconnected by an elastomer body having both a bell-shaped side wall and a central leg extending inside the side wall from the top of the elastomer body to a baseplate secured to one of the two strength members. The side wall has an aspect ratio lying in the range 2 to 8, while the central leg has an aspect ratio of less than 2, such that when a predetermined static axial load is applied to the support, the side wall is subjected to buckling and then presents substantially zero stiffness while the central leg is not subject to buckling.
