ABSTRACT:
A fluid-filled cylindrical elastic mount having an inner sleeve, an outer sleeve disposed radially outwardly of the inner sleeve with a predetermined radial spacing therebetween, and an elastic body interposed between the inner and outer sleeves for elastically connecting the inner and outer sleeves. The fluid-filled elastic mount has a generally annular fluid chamber formed between the inner and outer sleeves so as to extend over the entire circumference of the mount. The fluid chamber has a substantially constant cross sectional area over the entire circumference thereof, is filled with a non-compressible fluid having a kinematic viscosity of not higher than 100 centistokes, and undergoes substantially no deformation upon a rise in pressure due to the presence of a stopper portion provided in the chamber which may consist of a ring-like rigid member.
