SUPPLY SYSTEM OF INTERNAL-COMBUSTION ENGINE Russian patent published in 2015 - IPC F02M37/18 F02M59/20 F02M63/02 

FIELD: engines and pumps.

SUBSTANCE: offered invention relates to supply systems of internal combustion engines. The supply system (10) of the internal combustion engine (12) has a fuel priming pump (26), a high pressure pump (30) a batcher (36) located in the hydraulic system between the fuel priming pump (26) and a high pressure pump (30), a zero fuel-supply line (38) intended for bleed-off of fuel leaks filtering through the batcher (36). On the downstream batcher end (36), a suction device - Venturi nozzle (40) - is located. Besides, the system has a pressure regulating valve (52) intended for pressure regulation in the low pressure part located between the fuel priming pump (26) and the high pressure pump (30). The Venturi nozzle (40) is located in the feeding fuel-supply line laid to the pressure regulating valve (52).

EFFECT: pressure drop in the zero fuel supply line.
