ABSTRACT:
A fluid-filled resilient bushing is disclosed, which includes a resilient member interposed between inner and outer sleeves, and an elastically yieldable partition member disposed in an axial void which is formed in the resilient member and extends over an entire axial length of the same. The resilient member and the partition member cooperate with the outer sleeve to fluid-tightly define a pressure-receiving chamber and an equilibrium chamber, which are disposed opposite to each other in a vibration-input direction in which the bushing receives a vibrational load. The chambers are filled with incompressible fluid and communicate with each other through an orifice. The inner and outer sleeves are disposed in eccentric relation with each other in the vibration-input direction.
