VALVE NOZZLE FOR HIGH-PRESSURE INJECTION OF FUEL Russian patent published in 2001 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: in proposed valve nozzle with magnetic valve electric control is provided by control circuit divided into first circuit which controls many valve nozzles, common part and several second parts, each interacting, respectively, with each valve nozzle to control current supply to electromagnet of magnetic valve. Second parts of circuit contain mainly power elements and storage elements of electric circuit. They are located in control case between magnetic valve and electric connector of valve nozzle. EFFECT: improved economy owing to reduction of power consumption in nozzle control system, improved reliability. 6 cl, 1 dwg
