ABSTRACT:
A variable stage type carburetor provided with a venturi vane which is adapted to vary the venturi area in a venturi portion thereof, commensurate to the opening of a throttle valve. This carburetor features that, in the running condition where the opening of a throttle valve is considerably large and yet the quantity of intake air is relatively less, the venturi vane is forcedly displaced in a direction to be closed so as to increase the venturi negative pressure in the venturi portion, thereby enhancing the injection of fuel.
