Abstract
Abstract A vibration damper for rotating members consisting of a hub member and at least two annular inertia members mounted upon the hub member by elastic elements. The hub and inertia members include cylindrical surfaces concentric to the axis of hub member rotation and the elastic elements cooperate with these surfaces for mounting one inertia member upon the hub member in a vibration absorbing relationship, and the second inertia member is mounted upon a cylindrical surface defined on the previously mentioned inertia member by an elastic element creating a ''''series'''' relationship between the inertia members and the hub member.
