Bennett, D E

An air gas mixing device of the type used to mix gaseous fuel with air as an air/fuel mixture for discharge into an air intake conduit means of an internal combustion engine is described comprising: a housing having an air duct extending through the housing; an air valve for controlling the rate of air flow through the air duct; a primary fuel inlet in communication with the air duct for delivery of gaseous fuel for mixture with air flowing through the air duct; a fuel valve for controlling the rate of fuel flow through the fuel inlet; a first fuel valve actuator means automatically operated by a remote first fuel valve control signal for moving the fuel valve in an open position to predetermined degree in response to the first fuel valve control signal; and a second fuel valve actuator means automatically operated by a remote second fluid pressure control signal in response to a sudden increase in engine load demand for increasing the opening of the fuel valve independently of the movement of the fuel valve by the first fuel valve actuator means whereby the fuel valve is opened to a predetermined degree by the first actuating means in response to the first control signal and the opening thereafter increased by the second actuating means in response to the second fluid pressure control signal to quickly enrich the air-fuel mixture upon sudden increases in load demand.
