ABSTRACT:
A variable area venturi type carburetor has a movable wall that varies the venturi area. A fuel flow metering valve moves with the wall and has a flow splitter land straddled by a fuel inlet port to proportion flow of fuel under pressure to opposite sides of the land, part of the flow supplying fuel tubes to discharge fuel adjacent the venturi throat, with the remaining proportion of fuel being returned to the pump, the proportions varying as a function of the position of the splitter land and the shape of the inlet port traversed by the splitter land.
