ABSTRACT:
A method of manufacturing a fluid-filled elastic mount including an elastic body connecting an inner and an outer sleeve, and having a pressure-receiving and an equilibrium chamber which are filled with a non-compressible fluid and communicate with each other through an orifice. The method includes preparing an inner unit having an intermediate sleeve connected to the inner sleeve by the elastic body, and a pocket formed in the elastic body such that the pocket is open through the intermediate sleeve and has an axial dimension defined by axially opposite side walls of the elastic body. The method further includes placing the inner unit within a mass of the fluid, and press-fitting the outer sleeve on the inner unit so as to provide the pressure-receiving chamber filled with the fluid, while applying an axial force to at least one of the side walls in the axial direction of the mount, to thereby cause elastic deformation of the side wall or walls so as to expand into the pocket. The axial force is removed from the side wall or walls to increase the volume of the pressure-receiving chamber and thereby reduce the volume of the equilibrium chamber.
