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 adapted so as to form therewith at least two diametrically opposite sealed chambers (A, B) communicating together through a narrow channel (E), the whole of said chambers and said channel being filled with a damping liquid. The median portion of its internal frame (1) comprises a rigid seat for a mobile or deformable valve (6, 10), which valve has two opposite surfaces placed respectively in direct contact with the liquid volumes contained respectively in both chambers (A, B). The amplitude of the deflection movements of this valve are limited.
