FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed fuel injection device has fuel injection pump whose working space is connected at suction side with fuel tank through fuel feed line, and is connected at delivery side with high-pressure receiver by high- pressure line. Large number of fuel lines are laid to separate valve nozzles from high-pressure receiver. Device has also one delivery valve on fuel feed line and on high-pressure line preventing return flow of fuel from working space of pump into fuel feed line and from high- pressure line into working space of pump. Delivery valves of feed fuel line and high-pressure fuel lines are combined into common valve system. EFFECT: simplified design, improved reliability. 10 cl, 1 dwg
