FIELD: engines and pumps.
SUBSTANCE: proposed system comprises electrically driven fuel pump fuel feed main line communicated with pump outlet with booster-shutoff valve or means to distribute fuel among atomiser manifold, and additional line communicating pump inlet with its outlet. Proposed fuel pump is a displacement pump with fuel feed amount varied by varying electric drive rpm. Extra pipeline is provided with fuel constant flow valve composed of jet arranged in said line and spring-loaded control slide valve. Jet inlet and outlet are communicated with slide valve free and spring-loaded chambers. Slide valve groove edge and slide valve sleeve orifice make variable-section channel in said extra line.
EFFECT: higher accuracy of fuel proportioning, fuel bleeding for engine fuel system components.
