SYSTEM TO SUPPLY FUEL INTO AIRCRAFT INTERNAL COMBUSTION ENGINE Russian patent published in 2005 - IPC

FIELD: aircraft industry; internal combustion engines.

SUBSTANCE: proposed system consists of fuel tank, electric gasoline pump, filter, pressure reducing valve, fuel manifold with electromagnetic nozzles and control unit with parameters pickups. Fuel pump with mechanical drive is installed in series with electric gasoline pump. Electromagnetic valve is installed at inlet of fuel manifold with electromagnetic nozzles. Said electromagnetic valve, when de-energized, communicates space after pressure reducing valve through fuel meter with additional fuel manifold which accommodates hydraulically operated fuel nozzles. Fuel meter drain main communicates with drain main of pressure reducing valve.

EFFECT: improved reliability of fuel supply system by partial duplication and simplification.
