Patent ID: 7735812

Claim:
A kit of parts for vibration damping comprising: a vibration damping device having: a rim for engaging with walls of a mounting hole; an elastomeric body which is axisymmetric about an axis, said body extending radially outwardly of said rim to a periphery and having a base side, said body having a through hole coaxial with said axis; and an integrally bonded cup-shaped axisymmetric structure coaxial with said axis, said structure having a base portion adjoining the base side of said elastomeric body, a side wall adjoining the periphery of said elastomeric body, and an opening coaxial with said axis and encompassing the circumference of said through hole, wherein said elastomeric body has a groove encompassed by said side wall and extending coaxial with said axis and closer to said periphery than to said through hole; and one or more snubber member(s) adapted to be received by the groove in the elastomeric body, each snubber member being designed to vary the stiffness characteristics of the vibration damping device when inserted in the groove.
