Abstract
An apparatus for atomizing liquid fuel while mixing it with air, and varying the amount of each while maintaining a substantially constant fuel/air ratio for the intake manifold of an engine. The apparatus includes a frame ( ) forming a passage ( ) with a throat ( ), with a second wall ( ) of the passage being moveable toward and away from a stationary first wall ( ) of the passage to vary the cross-section of the passage and thereby vary airflow. A fuel-carrying tube ( ) has a proximal end ( ) fixed to the first stationary wall and has a distal portion ( ) that extends through a bore ( ) in the moveable wall and with the moveable wall being slideable around the tube. The tube has at least one aperture ( ) for flowing fuel into the passage, with the exposed aperture area being progressively increased as the moveable wall moves away from the stationary wall to flow a progressively increasing amount of fuel into the passage. The moveable wall is moved by a lever ( ) that can be moved by the throttle of the engine.
