摘要：A fluid-filled vibration damper includes a partition (21) which is vibratable toabsorb vibrations with small amplitudes. When vibrations with amplitudes greater than acertain amplitude level are continously applied over a certain period of time, thevibrations of the partition are substantially stopped. The fluid-filled vibration dampercomprises an attachment (7) adapted to be attached to a vibration source, a base (1)adapted to be attached to a structural member, an elastomeric member (10)

interconnecting the attachment (7) and the base (1), a diaphragm (12) disposed in eitherthe attachment or the base, the elastomeric member (10) and the diaphragm (12)defining therebetween a fluid chamber (S) filled with a fluid, a partition (21) disposed inthe fluid chamber and dividing the fluid chamber (S) into first and second fluid chambers(S1, S2), a passage (26) providing fluid communication between the first and second fluidchambers, and a stop assembly (20) disposed between the partition and the first fluidchamber (S1) and between the partition (21) and the second fluid chamber (S2) andspaced from the partition with a clearance therebetween, the stop assembly (20) limitingvibration of the partition (21) while allowing the partition (21) to move transversely withina predetermined range, the partition (21) having therein an auxilliary fluid chamber (A)having a variable volume and communicating with at least one of the first and second

fluid chambers (51, 52) the auxiliary fluid chamber (A) being expandable to reduce the theclearance between the partition (21) and the stop assembly (20) when the fluid flowsfrom said at least one fluid chamber (S1, S2) into the auxiliary chamber (A).
