摘要： The present invention involves a carburetor (10) including a carburetor body (12) having a throat (34), a fuel bowl (16) connected to said carburetor body, a conduit (32) extending from said fuel bowl to said carburetor throat, a variable volume primer chamber (42,44) communicating with said bowl through a priming passage; the carburetor characterized by: an extended prime fuel chamber (62) communicating with the throat through an extended prime fuel passage (74) and communicating with the fuel bowl through a fuel fill passage (68,70). The extended prime fuel chamber delivers additional fuel from start-up through warm-up periods of the engine. The extended prime fuel chamber is arranged such that, after activation of a priming bulb, fuel from the carburetor bowl is directed into the throat through a nozzle tube and also into the extended prime fuel chamber through a prime fill passage. Once the engine fires, the fuel in the extended prime fuel chamber then is also directed into the carburetor throat through an extended prime fuel passage disposed at a lower position in the extended prime fuel chamber than the point at which the prime fill passage connects to the extended prime fuel chamber.

摘要翻译：本发明涉及一种化油器（10），其包括具有喉部（34）的化油器本体（12），连接到所述化油器主体的燃料碗（16），从所述燃料碗延伸到所述化油器喉部的导管（32）可变容积底漆室（42,44），通过启动通道与所述碗连通; 所述化油器的特征在于：延伸的主燃料室（62），其通过延伸的主燃料通道（74）与所述喉部连通并通过燃料填充通道（68,70）与所述燃料箱连通。延长的主燃料箱从起动到发动机的预热期间提供额外的燃料。扩展的主燃料室被布置成使得在启动起泡泡之后，来自化油器碗的燃料通过喷嘴管被引导到喉部中，并且还通过主填充通道进入延伸的主燃料室。一旦发动机起动，则延伸的主燃料室中的燃料然后也通过设置在延伸的主燃料室中的下部位置处的延伸的主要燃料通道引导到化油器喉部中，该主燃料通道比主填充通道连接到延长燃油舱。
