OIL SYSTEM OF AIRCRAFT JET TURBINE ENGINE Russian patent published in 2016 - IPC F02C7/06 

FIELD: food industry.

SUBSTANCE: oil system of aircraft gas turbine engine (GTE) relates to aircraft engineering. Oil pump discharge line, connected to oil cavities of bearing supports of rotor, are communicated with main oil discharge line of pump oil of cavity accessory gear box via check valve, spring-loaded towards discharge line of pumps of oil cavities of bearing supports of rotor, resistance of which close to pressure differences generated by oil pumps of oil cavities of bearing supports of rotor and accessory gear box.

EFFECT: such design of oil system enables correction of hydraulic resistance in discharge lines of pumps driven by engine rotor, which enables to restore balance of supply and discharge of oil in accessory gear box and avoid overheating of oil in oil cavity of accessory gear box and oil pressure drop at engine inlet.
