Abstract
The invention relates to a hydraulic antivibration device having two rigid strength members interconnected by an elastomer body forming a working chamber and a compensation chamber which communicate via a narrow passage formed by two circularly-arcuate channels connected in series. The two channels are formed by two respective grooves formed in the two faces of a rigid body, the grooves being at least partially closed by two annular bearing surfaces clamped axially against opposite faces of the rigid body.
