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.
