Abstract: The deaerator includes a chamber that includes vortex generators that centrifuge the oil/air to separate the components and the chamber may operate in all attitudes. In addition wake separators mounted in the inlet of the chamber remove a large percentage of the air from the oil prior to entering the chamber and reintroduce the separated air component in the air removal tube. A dam in the air removal tube is located downstream of the inlet of the wake separated air to assure no oil is extracted from the air tube leaving the chamber. The wake separator consists of one or more tubes extending transversely to the flow of the oil/air stream and the air is removed through rearwardly facing apertures formed in the tube(s).

Abstract: The services normally associated with the lubrication oil tank used on aircraft are made dependent of each other by the judicious location of the various service housings, inlet ports and internal passages. The caps of the pressure fill port and overfill port are sequentially removable in order to prevent fill while the overfill port is blocked off. The overfill port and JOAP port are combined and internal valving automatically responds to the type of service called for.
