ABSTRACT:
A hydraulic anti-vibration support comprises at least one elastomer spring body made of a high temperature-resistant material which connects a first rigid strength member and a second rigid strength member. The first rigid strength member includes a piston which comprises a rod terminated by an end member, and a second rigid strength member has an opening which is traversed by said piston. A liquid-filled module is mounted inside a casing which is secured to the second rigid strength member, and includes a working chamber defined in part by a substantially dome shaped elastomer wall which has a central area in contact with the end member of the piston without any mechanical securing. Preferably, the high temperature-resistant material comprises silicone and is in non-adhesive contact with the first and the second rigid strength members.
