摘要
A sump evacuation system (90) for a gas turbine facilitates reducing oil leakage from bearing assembly sumps in a cost-effective and reliable manner. The engine includes at least one bearing assembly housed within a sump pressurization cavity (80). The sump evacuation system includes a sump pressurization cavity, a sump oil cavity (44), an air/oil separator (92), and an air pump (94). The bearing assembly and the sump oil cavity are coupled in flow communication with the sump pressurization cavity, and the air/oil separator is coupled in flow communication with the sump oil cavity. Furthermore, the air pump is coupled in flow communication with the air/oil separator.
