Claim 11:
12. A lubricant scavenge system for a gearbox of a tiltrotor aircraft, the gearbox being pivotable between an airplane-mode orientation and a helicopter-mode orientation and having a fluid sump therein, the system comprising:
first and second scavenge ports, each port in fluid communication with a selected portion of the sump for withdrawing fluid from the associated portion of the sump, the portions being spaced from each other; and
a valve for controlling a flow of fluid through each scavenge port;
wherein the valve allows a first flow rate through the first scavenge port and allows a second flow rate through the second scavenge port when the gearbox is in a first angular orientation; and
wherein the valve allows a third flow rate through the first scavenge port and allows a fourth flow rate through the second scavenge port when the gearbox is in a second angular orientation.
