A fluid filled resilient bushing assembly for rotary vibratory motion control, particularly adapted for use in a joint between a motion inducing member and a base member, having an elongate outer rigid sleeve member, an elongate inner rigid member rotatable with respect to the outer rigid sleeve member and a resilient means interposed between the inner and outer members. The resilient means defines at least two spaced chambers interconnected by an elongate restricted passageway filled with incompressible fluid. The bushing assembly further has a pressure differential inducing means creating a differential in the fluid pressure of the chambers due to the rotary motion of the inner rigid member to permit contraction of one of the chambers, expansion of the second chamber and fluid flow therebetween providing damping of the rotary vibratory motion.
