ABSTRACT:
A throttle valve has or cooperates with a metering wall or walls which function to limit the amount of air permitted to flow past the edge of the throttle valve when it is initially moved from its closed position. The amount of rotation of the throttle valve for a given change of air flow is thus increased enabling the output of a sensor such as a variable resistor to vary sufficiently to enable an accurate indication of the amount of air passing to the engine especially at frequently used relatively low throttle settings.
