FIELD: mechanical engineering; engines; fuel devices of fiesel engines. SUBSTANCE: with mechanical switch 19 turned on, current flows along electric wire 17 through turned on automatic circuit breaker 16 to electric motor 10 which provides operation of compressor 9. Compressor delivers compressed air along branch pins 11 to fuel tank 1. Under action of compressed air, fuel is delivered to fuel injection pump 6 through supply pipeline 3, bypass valve 21, coars and fine filters 4 and 5, respectively. Cutoff fuel is returned into fuel tank 1 along leakoff fuel pipe 8. EFFECT: enhanced reliability of operation. 1 dwg
