Buttner, H J

This patent describes a carburetor comprising a body defining an induction passage having upstream air valve means and downstream throttle means therein. The air valve means provides for delivery of fuel to the induction passage and has an air valve member normally biased towards a closed position but moveable between the closed position and an open position in response to varying air flow through the induction passage. The improvement described here comprises: the throttle means being mounted on shaft means extending along at least one side of the induction passage, and including an upstream surface portion extending from the shaft means towards the opposite side of the induction passage, and being inclined downstream when viewed in its closed position; and orifices being formed in the surface of the air valve member for discharging fuel into the induction passage, the orifices communicating with connecting means for connecting the orifices to a source of fuel.
