ABSTRACT:
A throttle body assembly comprises a throttle body having an induction passage therein with a pair of rotatively coupled, parallel shafts extending across the induction passage. A pair of blades are affixed to each shaft with each blade comprising a main blade section for selectively restricting the induction passage in accordance with shaft rotation and an auxiliary blade section which presents a curved confronting surface to an adjacent wall portion of the induction passage so as to preclude intrusion of any appreciable amount of induction air between each blade and the corresponding wall portion over the operative rotational range of the shafts.
