A system for lubricating a component of a gas turbine engine includes a supply pump to pump lubricant from a reservoir through a supply conduit to the lubricated component. The outer body de-icing circuit is fluidly coupled in series with the supply conduit. In addition, an oil return conduit extends from the lubricated component to the reservoir and an oil scavenger pump pumps lubricant from the lubricated component through the oil return conduit. Further, a valve is fluidly coupled in series with the supply conduit and the oil return conduit, and a bypass conduit extends from the valve to a location on the supply conduit downstream of the de-icing circuit. When lubricant is supplied to the valve, the valve directs lubricant flowing through the oil return conduit into the reservoir. When supply of lubricant to the valve is stopped, the valve directs lubricant flowing through the oil return conduit into the bypass conduit. 一种用于润滑燃气涡轮发动机的部件的系统，包括供应泵，以通过供应管道将润滑剂从储存器泵送到被润滑部件。外体除冰回路与供应管道串联地流体联接。此外，回油管道从被润滑部件延伸到储存
