ABSTRACT:
A fluid-filled elastic mount including a first support member and second support member, an elastic body interposed between the first and second support members, a closure member for partially defining a fluid chamber filled with a non-compressible fluid, a partition device for dividing the fluid chamber into a pressure-receiving chamber and an equilibrium chamber, a device for defining a restricted passage for restricted fluid communication between the pressure-receiving and equilibrium chambers, and a movable member which is supported deformably or displaceably in a load-receiving direction. The elastic mount further includes an operating device having a cup-shaped member for dividing the pressure-receiving chamber into a first section on the side of the first support member and a second section on the side of the partition device. The cup-shaped member cooperates with the elastic body to define an annular restricted portion which communicates with the first and second sections. The operating member further has an elastic member, and a resonance member elastically supported by the elastic member and having a first communication hole.
