ABSTRACT:
A carburetor for internal combustion engines has a toroidal fuel evaporation chamber which is defined by an outer cylindrical housing and an inner intake tube shorter than the housing. The carburetor further comprises a bottom wall or floor and an upper wall or roof, which together with other elements define the evaporation or wick compartment and a mixing chamber, as well as a plurality of intake orifices with adjacent inwardly opening valves in the upper wall or roof and about the periphery of the cylindrical housing in the region of the mixing chamber. Throttle plug means are reciprocal in guide means and cooperate with the upper wall member or roof to define a selectively variable throttle opening. A level control device maintains a pre-determined fuel level in the evaporative chamber wherein appropriate wick means are provided for the release of fuel vapor into the air drawn into the mixing chamber of the carburetor, and thence into the engine intake manifold.
