Abstract

The invention provides a hydraulic antivibratory support interposed between a vehicle chassis and engine, including a work chamber (A) and a compensation chamber (B) filled with liquid and joined together through a nozzle (19) whose section, which determines the frequency of the best damped oscillations, can be modified even during operation of the support. This nozzle is defined at least partially by a deformable wall (20) and modifications of the section of the nozzle are obtained by deforming the wall.
