Abstract
A lubrication system for lubricating gas turbine engine components and accessory components separately comprises first and second lubricant circulating circuits for separately feeding lubricant to the engine components and the accessory components. The system further includes a supply tank with first and second separate chambers respectively connected in fluid flow communication with the first and second lubricant circulating circuits. A filler port is defined in the tank for allowing the first chamber to be filled with lubricant. A filling and level maintaining circuit is connected to the first lubricant circulating circuit for directing a portion of the lubricant fluid pumped from the first chamber into the second chamber, thereby obviating the need for a second filler port.
