ABSTRACT:
A hydraulic antivibratory support is provided comprising a rigid base (4), a rigid annulus (1), a resilient annular support wall (6) sealingly connecting the base to the annulus and a flexible membrane (7) sealingly connected to the annulus, the inside of the sealed case thus formed being divided by a sealed dividing wall into two chambers connected together through a restricted passage, and a liquid mass filling the two chambers. A traction resistant cable section (13) is situated inside the support and is fixed to the case and to the rigid annulus so that the relative movements of these two elements away from each other are limited by said cable section being placed under traction.
