ABSTRACT:
A fluid-filled cylindrical elastic mount including an inner sleeve, an outer sleeve disposed radially outwardly of the inner sleeve, and a generally annular elastic body disposed between the inner and outer sleeves for flexible connection therebetween. The elastic body partially defines two fluid chambers filled with a non-compressible fluid. The fluid chambers are formed in diametrically opposite circumferential portions of the elastic body between the inner and outer sleeves. The elastic body has at least one orifice passage formed therethrough for fluid communication between the two fluid chambers, and extending through the elastic body, adjacent one of the inner and outer sleeves. The elastic body further has at least one void each formed between the corresponding orifice passage and the other of the inner and outer sleeves.
