ABSTRACT:
A variable venturi-type carburetor comprising a suction piston which has a tip face defining a venturi portion. The tip face has a flat upstream end portion. A raised wall is formed on the inner wall of an intake passage, which faces the tip face of the suction piston. The raised wall has a tip edge having an approximately V-shaped cross-section. The flat upstream end portion of the tip face of the suction piston cooperates with the tip edge of the raised wall for defining an approximately isosceles triangular-shaped air inlet control opening therebetween when the amount of air fed into the cylinder of an engine is small.
