A fluid-filled resilient bushing having inner and outer sleeves, and a resilient member interposed between the inner and outer sleeves for primarily damping and isolating vibrating applied in a first diametric direction of the bushing. The bushing has a pair of first fluid chambers disposed in mutually opposed relation with each other in the first diametric direction, a pair of second fluid chambers disposed in mutually opposed relation with each other in a second diametric direction perpendicular to the first diametric direction, and at least one orifice through which the pair of first fluid chambers communicate with each other, so as to permit a working fluid to flow between the first fluid chambers upon application of the vibrations. The bushing includes a pair of vanes fixedly supported on the inner sleeve so as to extend therefrom in the pair of second fluid chambers, respectively, toward the outer sleeve, such that the portions defining the second fluid chambers, and a periphery of each of the vanes cooperate to define a predetermined gap in a plane of said each vane parallel to an axis of the bushing structure. |
