PLANE FUEL SYSTEM Russian patent published in 2008 - IPC B64D37/00 

FIELD: engines and pipes.

SUBSTANCE: fuel system of the plane contains fuel cisterns, feed and before feed compartments, primer pipe, ejector pump of fuel transferring from fuel cistern to before feed compartment, ejector pump of fuel transferring from before feed compartment to the feed compartment, the tube system of feeding the active fuel, with installed valves. The system is connected to the device of overwork, installed on the plane, contains mess bowl, the devices of fuel level and devices of the cistern emptying. Every ejector pump of fuel transferring to before feed compartment is provided with hydraulic valve, controlled by the device of fuel level, to every part of tube system between hydraulic valve and the device of fuel level it is hooked up the electrical controlled valve, reducing the pressure after the signal from the device of the cistern emptying or after the signal of diminution of level overpressure of the overpressure device, restoring the pressure after the signal of the overpressure increasing.

EFFECT: it is reduced the active fuel consumption by shutting down the ejector pumps during the cistern emptying and during the action of the negative overpressure and increasing the time flight under the negative overpressure.
