Abstract
A fluid-filled elastic mount including an elastic body which is interposed between radially spaced-apart inner and outer sleeves and which at least partially defines a first pressure-receiving chamber containing a non-compressible fluid. A partition is provided for partially defining at least one second pressure-receiving chamber filled with the fluid. The partition includes a displaceable flexible layer which permits a pressure change in the first pressure-receiving chamber to be transmitted to the second pressure-receiving chamber or chambers. A variable-volume equilibrium chamber filled with the fluid is partially defined by a flexible diaphragm, and communicates with the first pressure-receiving chamber through a first orifice passage, and with each second pressure-receiving chamber through a second orifice passage whose ratio of a transverse cross sectional area to a length is larger than that of the first orifice passage.
