A throttle body defining a passageway and including a throttle valve formed by a pivoting plate is profiled to include a venturi nozzle whose converging wall lies adjacent the path of the plate periphery. The radius, and other characteristics of the converging wall reduces the change of flow rate throughout the low range of throttle travel to reduce sensitivity to throttle actuator position. Furthermore, the venturi nozzle profile is configured in accordance with standard engineering characteristics to avoid pressure differential which restricts air flow rate through the passage and maintains a high maximum flow rate through the throttle passage. Moreover, the profile can be formed by simple mold parts or simple machining apparatus for ease of construction.
