ABSTRACT:
Antivibration isolation device with hydraulic damping of radial elasticity, consisting of four concentric tubes bonded two by two to the elastic lateral walls, which by simultaneous fitting form two chambers connected by a long laminar passage for an inertial damping fluid, shunted by limited deformation of a thin membrane, to modulate the apparent dynamic rigidity as a function of the frequency. Process for the realization of such a device. The object of the invention is to provide antivibration isolation for machines or motor vehicles.
