ABSTRACT:
An air atomizing throttle body is formed with a single point fuel injector located above the inlet to the throttle body induction passage, the throttle body having an inverted cup-shaped sleeve valve, the lower edges of which cooperate with a stationary conical valve seat projecting radially into the induction passage to define a variable area flow path, and including idle speed air vents to equalize pressures on opposite sides of the sleeve valve to minimize the force needed to move the valve by a pressure operated bellows incorporated into the valve, the valve members forming a labryinthian type air/fuel flow path for the shearing of the fuel globules to atomize the same.
