Abstract
A hydraulic antivibratory support is disclosed comprising two rigid frames, an elastomer structure forming therewith two sealed chambers, a restricted passage causing the two chambers to communicate permanently with each other, a liquid mass filling the two chambers and the restricted passage, a rigid ferromagnetic movable member partially defining one of the two chambers, and electric coils for applying alternating forces to this movable member, said movable member being guided axially and the air gaps being isolated from the liquid. A control system is provided making the electric energization of the coils dependent on the axial movements of the movable member itself by means of a sensor so as to reduce movements of the movable member.
