Abstract
Abstract 1. Damper spring consisting of a helical spring (3) and of resilient elements (4) each of which is inserted between two adjacent turns of wire, characterized in that the faces (411, 421) of the said elements (4) in contact with the turns adhere to the wire so as to be inseparable therefrom and in that the said elements (4) are sized and made of a viscoelastic material so that the stiffnesses of the damper spring are substantially equal to those of the helical spring (3), the said elements (4) being used solely to damp high-amplitude oscillations at the resonance frequency of the helical spring (3).
