ABSTRACT:
The invention provides a hydraulic antivibratory support sleeve comprising two rigid tubular frames (1, 2), one surrounding the other and joined together by an elastomer body (3) adhered thereto and shaped so as to form therewith at least two sealed chambers (A, B) diametrically opposite in a direction Y separated from each other by a central dividing wall (6) and communicating together through a narrow channel (E), the assembly of the chambers and the channel being filled with a liquid. One at least of the sections, of its central dividing wall (6), separating the two chambers and connecting the two frames together is formed with a well (5) extending in direction Y, causing the two chambers (A and B) to communicate with each other, which well is closed by a mobile or deformable valve (4) associated with a device for limiting the amplitude of its deflections.
