ABSTRACT:
A gaseous fuel carburetor includes a gas flow control valve movable both by the engine intake air stream via a vane member in the intake air duct and by a fluidic (e.g., vacuum) actuator in the valve assembly, the actuator being controllable in response to engine load demand, whereby the total gas valve opening is responsive to intake air flow and engine load. A motion damper for the valve is included, and a dual gas/liquid fuel supply system is also described wherein the air vane can be retracted to a nonobstructing position relative to the air duct when the supply of gas fuel is ceased.
