Abstract
A device that corrects with ease and high precision any deviation of the fuel flow rate due to variation in the constituent components of a carburetor, and to improve the exhaust condition and operability of an engine. A carburetor in which the delivery channeland the suction channelof a fuel pumpare connected with the aid of an escape channel, and in which a portion of the delivery fuel is allowed to escape to the suction side in order to prevent pressure exerted on the fuel valveby the fuel delivered to the constant fuel chamberfrom the fuel pump, which operates by pressure pulses, from reaching or exceeding a specified level, wherein the escape channelis equipped with a manual control valvefor steplessly adjusting the surface area thereof. The quantity of fuel retained in the constant fuel chambercan be adjusted so as to achieve a predetermined fuel flow rate by changing the escape quantity of the delivery fuel and rendering the fuel valvemore resistant to opening or less resistant to opening.
