| 摘要 |
<p>The invention relates to a hydraulic anti-vibration bush comprising, on the one hand, two rigid tubular supports (1,2) of axis X surrounding one another and joined together through an elastomeric body (3) shaped so as to form with these supports at least two sealed pockets (A,B) diametrically opposite one another in a direction Y and communicating with one another through a narrow channel (4), which pockets and which channel are together filled with a liquid, and on the other hand, at one of its axial extremities, an annular work chamber (C) bounded in part by an elastic wall (7) resistant to axial compression. This bush also comprises at its other axial extremity an annular compensation chamber (D) bounded in part by a flexible annular diaphragm (12) while a narrow channel (13) directly connects the two annular chambers, and this channel and these two chambers are together filled with a fluid.
