Torsional dampers
First Claim
1. A torsional damper comprising at least first and second coaxial parts mounted to rotate relative to one another within a defined sector of relative angular movement, circumferentially disposed between said parts circumferentially acting elastic means comprising a plurality of elastic members some at least of which are associated with one another in series in a rest configuration of the damper assembly, and modulation means which, beyond a predefined degree of relative angular movement between said parts, bring about the parallel association with one another of at least some of said elastic members.

Abstract
A torsional damper comprising two coaxial parts with respective disks mounted for relative rotation, at least one guide ring and springs interposed circumferentially between the coaxial parts. The springs are divided into groups of at least two springs, with each spring individually housed in windows in the disks and guide rings. The springs are all engaged without circumferential play in the windows in the guide rings and each is engaged with circumferential play in the corresponding window in the disk of at least one of the coaxial parts.
