摘要

In this elastic against - plug incorporating a resonator and - the mechanical system mass - spring, of the type with a hydraulic amplifier of the displacement of the oscillating mass 7, the said mass is mounted between two return springs which are antagonists of which constitutes a hollow piston with a double face which is slidably mounted on two cylinders 6 coaxially opposite in a closed chamber filled with a liquid 10 in an internal tubular element 1 placed in an outer tubular element 2 with which it defines, at each end, a chamber 18, 26 filled with liquid, in which one of said cylinders 6, the said elements 1, 2 constituting the body of the counter - plug are mounted coaxially with respect to each other and fixed together at each of their ends in a sealed manner and for the bearings in the elastomer material.
