Lubricating oil supply system for gas turbines of aircraft engine, has valve device which opens connection line upstream to main oil pump by ventilation line of oil tank to oil line

摘要

The system (1) has an oil tank (4), a main oil pump (5), and an oil line (16) from the lower area of the oil tank for main oil pump. A valve device (6) is movable between two switching positions and is actuated reciprocally by an interchange from a positive to negative gravitational load. The valve device opens a connection line (18) upstream to the main oil pump by the ventilation line (17) of the oil tank to oil line in the switching position of negative gravitational load.
