Abstract
An oil leakage recovery system for recovering leaked oil in an oil system of a gas turbine engine The oil leakage recovery system includes a collecting reservoir having an inlet opening and an outlet opening each communicating with the oil system, a piston operatively mounted with the collecting reservoir and movable between a first position in which the piston is disposed away from the outlet opening to allow oil to leak from the collecting reservoir to the oil system and a second position in which the piston blocks the outlet opening to impede oil leaking from the collecting reservoir from the collecting reservoir to the oil system, and a pressure-controlled actuator system configured to move the piston to the first position when a pressure of the oil system is below a threshold pressure value and to the second position when the pressure of the oil system is above the threshold pressure value.
