<p>A fluid-flow restrictive plate or diaphragm (36) divides a primary damping-fluid chamber (15) into first and second main chambers (23,24) and is responsive to the amplitude of an input vibration for restricting flow of damping fluid between the main chambers (23,24) when the amplitude is greater than a predetermined amplitude. A secondary damping-fluid chamber (20) includes first and second sub-chambers (18,19). First, second, and third orifice passageways (30,31,33) define respective flow restrictive passages between the first main chamber (23) and the first sub-chamber (18), between the second main chamber (24) and the first sub-chamber (18), and between the second main chamber (24) and the second sub-chamber (19). The fluid-flow restrictive plate or diaphragm (36) is associated with the second and third orifice passageways (31,33) for creating at least three resonant vibration systems required to damp three different input vibrations including engine shake, idling vibration, and high-frequency vibrations. <IMAGE></p> |
