ABSTRACT:
A variable Venturi, condition responsive, carburetor wherein a throttle linkage operated movable Venturi element cooperates with a fixed annular Venturi element such that the amount of fuel flow through the carburetor is regulated by the position of the movable Venturi element and an annular Venturi passage. Fuel flow for the engine at idle by-passes the Venturi, flow for normal driving speeds is proportioned by the position of the movable Venturi element and fuel flow for high speed engine operation is provided through the movable Venturi element in accordance with the position of the movable element in the carburetor.
