Upper support for shock absorber in suspension system

An upper support for a suspension system, which is interposed between a body of a vehicle and a shock absorber of the vehicle, for elastically connecting the vehicle body and the shock absorber, comprising:

• a generally cylindrical inner rigid member to which said shock absorber is fixed;
• a generally cylindrical outer rigid member which is disposed radially outwardly of said inner rigid member and fixed to said body of the vehicle;
• at least one generally annular elastic body interposed between said inner and outer rigid members for elastically connecting the inner and outer rigid members, said at least one elastic body at least partially defining at least one fluid chamber which is filled with a non-compressible fluid and which is subject to a dynamic vibrational load that is applied between said inner and outer rigid members;
• and
• at least one resonance member each of which is accommodated in the corresponding one of said at least one fluid chamber, each said resonance member having an outer configuration substantially corresponding to an inner shape of said corresponding one fluid chamber, and being secured to one of said inner rigid member and said outer rigid member, each said resonance member cooperating with an inner wall surface of the corresponding fluid chamber to define a resonance portion which has predetermined dimensions, and through which said non-compressible fluid is forced to flow upon application of said dynamic vibrational load.
