ABSTRACT:
An air-air/fuel throttle body is provided with a secondary throttle valve of a differing diameter and operating in a different cross-sectional area of the throttle body induction passage, the upstream throttle valve being positively connected to the vehicle accelerator pedal to assure a like opening or closing movement of the latter throttle valve upon movement of the accelerator pedal, the construction assuring that main control of the flow of air and changes in manifold vacuum will be retained by the lower smaller diameter servo operated throttle valve operating in a smaller cross-sectional area.
