ABSTRACT:
A vibration damping bushing having an energy absorbing sleeve positioned about an inner sleeve and within an outer sleeve. The energy absorbing sleeve has first and second cavities positioned diametrically opposed along the axis of force applied to the bushing, and has a connecting passageway interconnecting the cavities, these cavities containing a vibration damping fluid. The passageways serve as restrictive flow orifices to restrict the flow of the fluid between the cavities, and to thereby dampen the vibration of the outer sleeve with respect to the inner sleeve.
