ABSTRACT:
A fluid-filled elastic mount having a first and a second support structure, an elastic body interposed between the two support structures, a partition member cooperating with the elastic body to define a pressure-receiving chamber, a flexible diagraphm cooperating with the partition member to define an equilibrium chamber, and a resonance member fixedly disposed in the pressure-receiving chamber and including a flexible film which at least partially defines an air chamber. The elastic mount includes a pressure control device for changing the pressure in the air chamber, thus changing the vibration damping or isolating characteristics for the elastic mount.
