Abstract
A bearing compartment assembly includes a bearing compartment with a bearing and a plenum, a buffer system that supplies pressure to an exterior of the bearing compartment, and a reactive volume vessel connected to the bearing compartment. The reactive volume vessel has a displaceable member that is movable between two positions, one of which adds additional volume to the bearing compartment.
