ABSTRACT:
A fluid-filled elastic mount for flexible connection of two members, including a first 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 partition assembly for dividing the fluid chamber into a pressure-receiving chamber and an equilibrium chamber, and device for defining a restricted passage for restricted fluid communication between the pressure-receiving and equilibrium chambers. One of the first and second support members has a first abutting surface which extends substantially perpendicularly to the load-receiving direction, and a second abutting surface substantially perpendicular to the first abutting surface. The elastic mount is provided with a stopper member secured to the other of the first and second support members. The stopper member includes a stop portion which is spaced apart from the second abutting surface in a direction perpendicular to the load-receiving direction. The stop portion is held in pressed abutting contact with the first abutting surface in the load-receiving direction, whereby the elastic body is pre-compressed in the load-receiving direction.
