GAS-TURBINE ENGINE OIL SYSTEM Russian patent published in 2009 - IPC F02C7/06 

FIELD: engines and pumps.

SUBSTANCE: oil system of gas-turbine engine is related to the field of aeronautical propulsion engineering and makes it possible to avoid wasteful loss of lubricant through nozzle of air bleeding installed in loop of siphon lock. Oil system comprises oil cavities with points of lubrication and cooling of friction units and siphon lock installed in manifold of oil supply. Loop of siphon lock is connected by manifold to jet of air bleeding installed in air part of any oil cavity and arranged in the form of jet nozzle orifice directed to any of its lubrication points.

EFFECT: reduction of pressure pump capacity losses, reduction of its weight and increased reliability of friction units operation due to better oil purification from air in oil tank.
