ABSTRACT:
Elastic tuning, spacing and sealing rings substantially fill annular grooves in a ring shaped inertia mass and face toward and into engagement with the body of supporting disk means extending radially into an annular working chamber defined by the inertia mass, the chamber being substantially filled with a viscous damping medium. Annular retaining flanges along the radially inner sides of the grooves assist in mounting the elastic rings in concentric relation to one another and to the working chamber and protect the rings against intrusion of dirt and contaminants. The grooves are partially unfilled and provide damping medium reservoirs about the radially outer sides of the elastic rings.
Several optional configurations and combinations are disclosed to meet practical considerations.
