Suppression of vibrations in systems ; Means or arrangements for avoiding or reducing out-of-balance forces, e.g. due to motion; Suppression of vibrations in rotating systems by making use of members moving with the system using masses freely rotating with the system, i.e. uninvolved in transmitting driveline torque, e.g. rotative dynamic dampers the rotation being unlimited with respect to driving means with a dry-friction connection
