ABSTRACT:
A hydraulic antivibration support comprises an annular elastomer body surrounding a central axis and interconnecting a first support member and a support plate both of which are likewise annular. The elastomer body has two concentric annular cavities closed by the support plate, and constituting a working chamber and a compensation chamber which is radially defined on the outside by a thin side wall of the elastomer body, said two chambers being filled with liquid and being interconnected by a constricted passage which is defined in part by a channel-section piece located in one of the two chambers.
