Abstract
Structure for preventing cavitation and/or starvation in an oil film squeeze annular damper for dampening the high energy vibrations occasioned by a rotating shaft by including a plurality of judiciously located inlets to the annular damper so as to place in continuous communication the low pressure portion of the annulus with the supply source. Three inlet ports equally spaced about the circumference of the annulus disclose an exemplary supply system wherein each inlet includes a check valve for preventing backflow from the annulus.
