ABSTRACT:
A fluid filled resilient bushing assembly for vibration control, particularly adapted for use in supporting a torque strut or an automobile suspension system, which comprises an elongate inner rigid member and a elongate outer rigid sleeve member, an impact absorbing member interposed between the inner member and outer sleeve member filling the annular space therebetween and a resilient end wall means interconnecting and sealing said inner member and outer member. The impact absorbing member together with the inner and outer members are resilient wall means defines two spaced fluid chambers and two restricted passageways connecting said fluid chambers. The chambers and passageways contain an incompressible fluid. Disposed within at least one restricted passageway is a flow control means for controlling the resistance to flow of the fluid between the chambers.
