摘要： A carburetor has a choke system including a bimetallic spring that biases the choke valve closed with a force that increases with decrease in temperature. A hot air tube connected from an exhaust manifold heat stove to the intake manifold flows hot air past the spring to warm it as the engine warms. An electrical heater is activated above a predetermined temperature to provide supplemental heat to the spring to pull off the choke faster than by use of the hot air alone. A further manifold vacuum actuated switch energizes the heater below the predetermined temperature whenever the manifold vacuum drops as a result of altitude changes below a level indicating insufficient hot air flow past the bimetallic spring to warm it.
摘要翻译：化油器具有包括双金属弹簧的扼流系统，该双金属弹簧以随着温度降低而增加的力而使阻塞阀闭合。从排气歧管加热炉连接到进气歧管的热风管将热空气流过弹簧，以随着发动机的加热而加热。在预定温度以上激活电加热器以向弹簧提供补充热量，以比单独使用热空气更快地拉出扼流圈。当歧管真空度由于高度变化低于表示不足够的热空气流过双金属弹簧以使其加热时，歧管真空度下降，进一步的歧管真空致动开关将加热器激励器低于预定温度。

摘要： A four-barrel (4V) carburetor has a primary throttle plate shaft mounting two primary bore throttle plates, and two secondary throttle plate shafts each mounting a secondary throttle plate, the two secondary shafts having a limited interconnection in one embodiment, and being completely independently mounted in a second embodiment, to assure secondary throttle plate seating repeatability minimizing leakage of air past the plates.

摘要： A carburetor float bowl has a two-stage fuel inlet valve consisting of a small valve providing finite control for low rate of flow into the float bowl, and a larger valve actuated by the smaller valve to provide a relatively unrestricted opening between the fuel inlet and float bowl interior to permit operation of the fuel pump essentially at its full capacity if desired.
