Patent ID: 7341244

Claim:
A hydraulic anti-vibration support for interconnecting first and second rigid elements that are to be united in order to damp and filter vibration between said elements at least along a main vibration axis, the support comprising: a first rigid strength member for securing to the first rigid element, including a piston which comprises a rod substantially disposed coaxially along the main axis and an end member disposed at the end of the rod remote from the first rigid element, said end member extending substantially radially perpendicular to the main axis; a second rigid strength member for securing to the second rigid element, having a first side which faces the first rigid strength member and a second side in the opposite direction relative to the main axis and being provided with an opening traversed by said piston; at least one first elastomer spring body made of a high temperature-resistant material and connecting the first and second rigid strength members, disposed on the first side of the second rigid strength member; a casing secured to the second rigid strength member and extending on the second side of said strength member; and a liquid-filled module mounted inside said casing, comprising: a liquid-filled working chamber delimited on a first side 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 to said end member, a liquid-filled compensation chamber which is put into communication with the working chamber via a constricted passage, a partition member that separates said working and compensation chambers that includes said constricted passage.
