ABSTRACT:
A fluid-filled resilient bushing having an annular resilient member radially compressed between an inner rigid sleeve and an outer rigid sleeve concentric with the inner rigid sleeve. The resilient member has a plurality of recesses interconnected through an orifice, and the outer rigid sleeve cooperates with the recesses to define plural pockets which are filled with a fluid for a damping effect through resistance of flow thereof through said orifice. The bushing comprises a radial stop member of a predetermined height secured to the inner rigid sleeve and extending into the pockets toward the outer rigid sleeve. The stop member includes abutment end portions disposed in said pockets for abutting contact with the outer rigid sleeve upon application of a high load to the bushing.
