Abstract
A fluid filled vibration isolator of the type having upper and lower chambers separated by a partition having an inertia track passageway and a decoupler assembly permitting fluid to bypass the inertia track passageway at certain amplitudes. The decoupler assembly includes a plurality of wafers loosely contained within a cavity in the partition. The wafers have a predetermined density and occupies less than the entire cavity when at rest therein. At low amplitudes of vibration, the plurality of wafers oscillates in a dispersed condition as the fluid oscillates through the screened cavity essentially bypassing the inertia track passageway between the chambers. As the amplitude of vibrations increase beyond a certain level, the plurality of wafers compacts alternately against the screens to throttle flow therethrough and thereby cause the fluid to oscillate in the inertia track passageway.
