FUEL SUPPLY SYSTEM FOR DIESEL Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: system comprises fuel tank 1, corse fuel filter 2, fine fuel filter 6, fuel flow rate controller 3, high pressure pump 10 with connecting pipes of cutting-off 11 and delivery 9 spaces, additional fuel pump 8, pickup 14 of operation regime mounted on pump 10, electric and hydraulic valve 12, suction manifold 13 of the engine with a sprayer, and electric circuit 15 made as power source, controller circuits 3 and pickup 14. The system also has a relay connected in circuit 15 for controlling valve 12. Controller 3 is constructed as a fuel passage with the throttle, by-pass controlled passage and two interconnected passage with a liquid- metal contact alloy and controlled electrode mounted for interaction with the liquid-metal contact alloy, check valve mounted downstream of controller 3, and catcher 5 of the liquid-metal contact alloy interposed between the controller of fuel flow rate and the check valve. The first of two interconnected passages is connected to the fuel passage upstream of the throttle. The second passage is connected downstream of the throttle. The control electrode is mounted in the first passage and electrically coupled with electric circuit 15. EFFECT: enhanced reliability. 3 dwg
