FIELD: engines and pumps.
SUBSTANCE: invention can be used in internal combustion engines. Fuel feed system comprises variable-output fuel feed pump, high-pressure plunger pump 10 with casing 15 and plunger drive arranged therein. System fuel path with first section for communication between fuel tank and fuel feed pump, second path for communication between fuel feed pump and high-pressure plunger pump and third section for communication between said plunger pump 10 with ICE. Fuel path second section branches in first channel to feed fuel to high-pressure plunger pump inlet and to directly communicate fuel feed pump with high-pressure plunger pump. Second channel 12b feeds a portion of fuel to plunger pump case and communicates fuel feed pump with case 15. It allows fuel flow via at least one calibrated orifice 27.
EFFECT: simplified design, lower costs.
