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;
• a pair of annular elastic bodies interposed between said inner and outer rigid members for elastically connecting the inner and outer rigid members, each of said elastic bodies having an annular recess at least partially defining an annular fluid chamber which is filled with a non-compressible fluid;
• an annular partition member accommodated in said fluid chamber, such that said partition member is fixed to one of said inner and outer rigid members, and elastically connected to the other of said inner and outer rigid members through said elastic bodies, so as to radially extend from said one rigid member toward said other rigid member, and such that said fluid chamber is divided by said partition member into two sections which undergo relative volumetric changes when a vibrational load is applied between said inner and outer rigid members, said partition member having at least one orifice passage which allows said non-compressible fluid to flow therethrough between said two sections of said fluid chamber upon application of said vibrational load;
• and
• a pair of inner support members and a pair of outer support members, said pair of elastic bodies being secured to the corresponding inner support members and the corresponding outer support members so as to provide a pair of intermediate assemblies, the inner support member of each of said intermediate assemblies being fixed to said inner rigid member while the outer support member of said each of the intermediate assemblies being fixed to said outer rigid member, said partition member being gripped between one pair out of said pair of inner support members and said pair of outer support members, and between said pair of elastic bodies, said annular recess of the elastic body of each one of said intermediate assemblies and said annular recess of the elastic body of the other of said intermediate assemblies cooperating with said partition member to define said two sections of said fluid chamber, respectively.
