ABSTRACT:
The invention relates to a hydraulic antivibration sleeve comprising two tubular rigid strength members, one surrounding the other, the strength members being connected together by an elastomer body which defines two sealed pockets that communicate with each other via two narrow channels, the two pockets and the narrow channels being filled with liquid. The elastomer body is molded and bonded onto the two strength members, and each sealed pocket is constituted by a blind hole formed inside the elastomer body and opening out to one of the ends of the body, the elastomer body further including a collar which extends outwards from the inner strength member and which is fixed in sealed contact against a flange of the outer strength member, thereby closing the two pockets and the narrow channels.
