Abstract
An oil system for an aircraft engine includes an oil tank, an engine component in fluid communication with the oil tank, a scavenge pump, and a manifold disposed inside the scavenge pump housing and fluidly connecting the engine component to the scavenge pump. The manifold includes a fluid passage, extending between a manifold inlet and a manifold outlet, and including a first bend, upstream, and a second bend. The first bend includes an oil isolator and the second bend includes an air offtake. The oil isolator separates an oil fraction from the fluid received from the engine component at the first bend and directs the oil fraction to the scavenge pump, and the air offtake separates an air fraction from the fluid at the second bend and directs the air fraction away from the scavenge pump.
