Abstract
A hydraulic antivibratory support sleeve is provided 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 diametrically opposite sealed pockets (A,B) communicating together through a narrow channel (E), the assembly formed by said pockets and said channel being filled with a damping liquid (L), the pockets being in the form of cavities formed axially in at least one solid annulus. These cavities (A,B) open respectively into two separate annular chambers (C,D) and these two chambers are joined together exclusively by the narrow channel (E) which extends axially or helically.
