Abstract
A fluid-filled elastic mounting structure including a first fand a second support members disposed in spaced-apart relation with each other in a load-receiving direction, an elastic body elastically connecting the support members, a closure member secured to the second support member, so as to define therebetween a fluid chamber filled with a non-compressible fluid between the elastic body and the second support member, a partition assembly disposed within the fluid chamber, so as to divide the fluid chamber into a pressure-receiving chamber, and an equilibrium chamber, and a first orifice for fluid communication between the two chambers. The partition assembly has an opening communicating with the two chambers. A first and a second movable member are disposed within the opening of the partition assembly, such that the two movable members are spaced apart from each other in the load-receiving direction so as to define an intermediate chamber. A second orifice is formed in association with one of the movable members, for fluid communication of the intermediate chamber with the pressure-receiving or equilibrium chamber.
