Abstract

PURPOSE:To enable increasing of air-fuel mixture only when occasion demands and to improve fuel consumption, by a method wherein a power fuel feed system is formed with a system, which is operated in response to a suction negative pressure value, and a system which is operated in response to a throttle valve, and the latter system is actuated when the throttle valve is almost fully opened. CONSTITUTION:A moving body 3 for throttle, which forms a varying venturi between a throat part 2 and the moving body, is vertically movably contained in a housing 1 having a vertically extending columnar air passage and the throat part 2 formed with upper and lower members 21 and 22, and is moved through a ring coupled with a shaft 31 at the lower end thereof. Further, a first power fuel feed system, which is connected to an annular orifice 4, being open to the narrowmost part of the throat part 2 and is actuated by means of a suction negative pressure, and a second power fuel feed system which is actuated through a lever 52 in response to the movement of the moving body 3. The second power fuel feed system is adapted to be actuated when a throttle is almost fully opened.
