    Abstract: A carburetor having a constant level fuel supply and a mixing conduit has a throttle valve mounted above the fuel level. Two fuel supply circuits are provided. A first fuel circuit discharges through a nozzle located adjacent the high edge of the throttle valve and a second fuel circuit discharges fuel at a point located above the low edge of the throttle valve. The high and low edges referring to the position of the throttle when in curb idle position.

    Abstract: A carburetor having the usual throttle valve is also equipped with a butterfly valve surrounding the main fuel boost venturi (venturi valve). The venturi valve is linked to the throttle valve in such a manner as to begin opening movement shortly after the throttle valve begins to open. Air velocity over the main fuel nozzle approaches a maximum as the venturi valve begins to open and remains substantially constant thereafter to promote most efficient mixing of fuel and air.

    Abstract translation: 具有通常节流阀的化油器还配备有围绕主燃料升压文丘里管（文丘里阀）的蝶阀。 文丘里阀以节流阀开始打开后立即开始打开运动的方式连接到节流阀。 主燃料喷嘴上方的空气流速接近最大值，因为文丘里阀开始打开，并在此之后保持基本恒定，以促进燃料和空气的最有效混合。
