A hydraulic anti-vibration support intended to be interposed for damping purposes between first and second rigid elements, this hydraulic anti-vibration support comprising: - a first frame and a second frame intended to be fixed to the two rigid elements to be joined, - an elastomeric body which connects the first frame to the second frame and which at least partially defines a working chamber, - a first deformable compensation chamber, - a second deformable compensation chamber, - a constricted passage extending longitudinally between a first end communicating with the working chamber and a second end communicating with the second compensation chamber, - the working chamber, the first compensation chamber, the second compensation chamber and the constricted passage forming a hydraulic volume filled with liquid, wherein the constricted passage includes an intermediate opening communicating with the first compensation chamber, the constricted passage having a first section which extends longitudinally between the first end and the intermediate opening and a second section which extends longitudinally between the intermediate opening and the second end and wherein the working chamber, the first compensation chamber and the second compensation chamber are superimposed along a central axis, the working chamber being separated from the first compensation chamber by a rigid partition, the hydraulic anti-vibration support being characterised in that the first compensation chamber is separated from the second compensation chamber by an intermediate elastomeric membrane substantially perpendicular to the central axis, and the second compensation chamber is delimited between the intermediate elastomeric membrane and an elastomeric bellows. - a first frame and a second frame intended to be fixed to the two rigid elements to be joined, - an elastomeric body which connects the first frame to the second frame and which at least partially defines a working chamber, - a first deformable compensation chamber, - a second deformable compensation chamber, - a constricted passage extending longitudinally between a first end communicating with the working chamber and a second end communicating with the second compensation chamber, - the working chamber, the first compensation chamber, the second compensation chamber and the constricted passage forming a hydraulic volume filled with liquid, wherein the constricted passage includes an intermediate opening communicating with the first compensation chamber, the constricted passage having a first section which extends longitudinally between the first end and the intermediate opening and a second section which extends longitudinally between the intermediate opening and the second end and wherein the working chamber, the first compensation chamber and the second compensation chamber are superimposed along a central axis, the working chamber being separated from the first compensation chamber by a rigid partition, the hydraulic anti-vibration support being characterised in that the first compensation chamber is separated from the second compensation chamber by an intermediate elastomeric membrane substantially perpendicular to the central axis, and the second compensation chamber is delimited between the intermediate elastomeric membrane and an elastomeric bellows.
