Abstract
The invention relates to a hydraulic vibration-damping mount including a first rigid reinforcing member (1) and a second rigid reinforcing member (2), an elastomeric body (3) which includes, on the one hand, a thick wall (4) joining the two rigid reinforcing members to one another and partially delimiting a working chamber (A), and, on the other hand, a thin wall (5) which partially delimits a compensation chamber (B) connected to the working chamber by a narrow duct (C), the two chambers and the narrow duct being filled with a liquid, the second reinforcing member being a plate one face of which is secured in leaktight fashion to the elastomeric body in order to delimit, together with the latter, the two chambers and the narrow duct, the thin wall substantially exhibiting the shape of a bell only the edge (5.sub.1) of which is secured to the second reinforcing member.
