<p>System (111) consists of a helical spring (11) and of at least a pair of spacing elements (10) made of an elastomer and inserted between adjacent turns (11a,11b) of said spring, the height of said spacers being, in the direction of axis (K) of the spring, equal to the distance, at rest, between turns (11a,11b), said spacers being symmetrically arranged between said turns and equally spaced along the whole circumference of spring (11), no spacers being found at least between such turns, as are next to those between which they are inserted and comprising means (13,12) to securely connect, in a fixed position and on opposite sides, spacers (10) to turns (11a,11b). <IMAGE></p> |
