SYSTEM OF ENGINE FUEL SUPPLY Russian patent published in 2008 - IPC F02M37/22 G05D27/02 G01F1/12 

FIELD: engines and pumps.

SUBSTANCE: system of engine fuel supply consists of fuel tank wherein the following is installed: a level meter connected to the inlet of a "fuel-water" level regulator, and a control valve to flow out commodity water; the said valve is connected to a control outlet of the regulator. The level meter is made as two sensors of the fuel level, located in a portion of the lowest allowable fuel level mainly at opposite sides of the tank and one water level sensor located at the flow out level. The control valve is assembled so as to provide a positive feedback with the regulator upon receiving a signal on water presence and a negative feedback when there is no signal entry. At the moment of a positive feedback and water flow out the regulator is programmed to let out not more than 100 kg of fuel.

EFFECT: invention provides simplification of the design and economy of fuel due to avoiding excessive overflow of fuel at a regular flow out of commodity water.
