Abstract
A damper film bearing assembly for supporting a rotatable shaft includes a bearing housing having a longitudinal opening passing therethrough for receiving the rotatable shaft. The bearing housing also has at least one radial recess formed in an outer surface thereof, the recess having a floor. The assembly further includes at least one support piston slideably disposed within the recess in the bearing housing, the support piston slideable within the recess radially toward and away from a central longitudinal axis of the rotatable shaft. At least one resilient element is disposed within the recess in the bearing housing between the floor of the recess and the support piston, the resilient element biasing the support piston away from the axis of the rotatable shaft.
