Abstract

PURPOSE:To drive an air quantity control needle valve, provided in a bypass air passage, and a fuel control needle valve, provided in a fuel passage, with a single solenoid device, by arranging the air quantity control needle valve and fuel control needle valve so that their displacement direction may be on an equal line. CONSTITUTION:Since an air needle valve 46, provided in a bypass air passage 18, output shaft 48B, driving the air needle valve 46, proportional solenoid device 48, driving the output shaft 48B, output shaft 48A, dirven by the proportional solenoid device 48, and a fuel needle valve 42, driven by the output shaft 48A and provided in a fuel passage 32, are arranged on a same line simultaneously the fuel needle valve 42, air needle valve 46 and the output shafts 48A, 48B are separately constituted, after arranging each needle valve 42, 46, if the proportional solenoid device 48 is assembled, the output shafts 48A, 48B can be contacted to each needle valve 42, 46, and the necessity for alignment of each orifice 40, 44, needle valves 42, 46 and the output shafts 48A, 48B can be all eliminated.
