Abstract
A fuel/air metering system with an air throttle valve and fuel valve positively linked with the flow crossectional area of each valve proportional to the other. The air pressure drop across the air throttle valve is sensed and a corresponding fuel pressure drop is computed. A servo valve in series with the fuel valve is controlled so that the pressure drop across the fuel valve corresponds to this computed value.
