Abstract
In an engine air assisted fuel injection system, it is desirable to provide a first range of air flow during engine idle and at low loading conditions. At greater engine speeds and higher loading conditions, a substantially greater second range of air flow is desired. This flow characteristic is achieved by the subject air metering device having dual valve members mounted on an axially positionable shaft. The valves are mounted so that initial movements of the shaft opens only one valve to provide flows within the first range. Further movement of the shaft then opens the second valve to provide flows within the second range.
