ABSTRACT:
A method of oil flow management for a gas turbine engine includes moving oil from a tank to a compartment using a pressure pump, moving oil from the compartment to the tank using a scavenge pump, and at least temporarily increasing a rate at which oil is moved with the scavenge pump by a greater amount than a rate at which oil is moved with the pressure pump to create at least a partial vacuum to negatively pressurize the compartment to reduce oil leakage.
