ABSTRACT:
A fluid-filled elastic mount for flexible coupling of two members includes a first support member and a 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 first partition device for dividing the fluid chamber into a pressure-receiving chamber and an equilibrium chamber, and a device for defining a first restricted passage for restricted fluid communication between the pressure-receiving chamber and the equilibrium chamber. The fluid-filled elastic mount further includes a second partition member having a peripheral portion secured to an intermediate portion of the elastic body. The second partition member is adapted to divide the pressure-receiving chamber into a first section formed on the side of the first support member, and a second section formed on the side of the first partition device, and has a second restricted passage for restricted fluid communication between the first and second sections of the pressure-receiving chamber.
