ABSTRACT:
Charge forming apparatus such as a carburetor of the fluid jet type in which fuel is supplied to a pair of tubular members, which may be of equal or different diameters, disposed across a housing opening through which air flows, the velocity of which is controlled by a throttle valve or damper means. Each tubular member is constructed with a generally upwardly directed slot or fuel gap, such that the air strips fuel therefrom. Excess fuel from the tubular members is returned to the source. In the specific apparatus, one tubular member is located upstream in the housing from the other, the lower tubular member being located closely adjacent to the location of initial opening of the air throttle valve or damper. The throttle valve or damper may be of the iris type or of the type having a pair of vanes pivoted outwardly of the center thereof, so as to initially open at the center thereof.
At small throttle openings, air flowing to the engine is concentrated over the fuel gap of the lower member. This results in high air velocities at low air flow rates, which will provide sufficient fuel being stripped from the slots for the engine at idle and light loads.
