Patent ID: 8764867

Claim:
An oil flow management system in an aircraft comprising: a breather line coupled to an engine included in the aircraft, the breather line receiving a gaseous mixture including oil and gases from the engine included in the aircraft; a separator included in the aircraft, the separator having an input port coupled to the breather line and including a collection surface and an output port, the separator configured to receive the gaseous mixture from the breather line and separate the mixture into an gaseous component directed toward the output port and into an oil component directed toward the collection surface; an output breather line coupled to the output port of the separator, the output breather line configured to direct the gaseous component in a direction away from an exterior surface of a fuselage of the aircraft; a unidirectional valve included in the aircraft, the unidirectional valve having an inlet coupled to an orifice of the collection surface, the unidirectional valve including a weighted bearing configured to move within the unidirectional valve, the weighted bearing configured to open a channel from the inlet to an outlet when a plane including the inlet is above a plane including the outlet and the weighted bearing configured to block the channel from the inlet to the outlet to prevent the oil component from flowing from the outlet toward the inlet when the plane including the inlet is below the plane including the outlet; and a reservoir included in the aircraft and coupled to the outlet of the unidirectional valve, the reservoir configured to receive the oil component from the unidirectional valve.
