Abstract
PURPOSE: To facilitate atomizatio of fuel in a variable venturi carburetor in which bleed air is feed-back controlled by introducing air from a small hole formed through the outer peripheral wall of a mixing chamber.
CONSTITUTION: The rate of air-fuel mixture to be injected into a venturi portion 11 is determined by the movement of a suction piston 7, on the top end of which a metering needle 5 is fixed. Into a jet portion 6 through which the needle 5 is advanced and retreated, feed-back controlled bleed air is admitted through a throttle 16 of an air passage, while fuel is introduced via a throttle 18. A by-pass air passage 17 communicating to a space 26 behind the needle 5 is formed upstream the throttle 16. Through the outer peripheral wall of a mixing chamber 19 into which air and fuel are introduced, a small hole is provided in such a way that air is satisfactorily mixed with fuel and by-pass air is introduced from an annular space 26 behind the hole 20.
