Patent ID: 7396003

Claim:
A fluid-filled vibration-damping device for elastically connecting two members in a vibration damping fashion, comprising: a first mounting member fixable to one of the two members; an elastic body bonded at one of opposite end portions thereof to said first mounting member and having a recess open in an other one of opposite end portions thereof; a second mounting member of cylindrical configuration fixable to an other one of the two members and bonded on an outer circumferential surface of said other one of opposite end portions of said elastic body; a diaphragm whose peripheral portion is supported by an inner circumferential surface of said second mounting member so that said diaphragm cooperates with said elastic body to define therebetween a fluid chamber filled with a fluid; a partition member whose peripheral portion is supported by said inner circumferential surface of said second mounting member so that said partition member divides said fluid chamber into a primary fluid chamber and an auxiliary fluid chamber, said partition member including a metallic orifice-defining member adapted to at least partially define an orifice passage for fluid communication between said primary and auxiliary fluid chambers, and a movable rubber plate disposed in a central hole formed through said orifice-defining member; and a coating rubber layer formed on a surface of said orifice-defining member at a primary-fluid-chamber-defining area, wherein said primary-fluid-chamber-defining area is substantially entirely coated by said coating rubber layer.
