    • A carburetor includes a main fuel path connected to a main nozzle and a slow fuel path connected to a slow port. The main fuel path and the slow fuel path are separated from each other and are independently communicated to a constant fuel chamber below a fuel level of the fuel chamber. The slow fuel path includes a first slow jet located above the fuel level and a second slow jet located in the downstream of the first slow jet. A opening size of the second slow jet is smaller than that of the first slow jet, and the first and second slow jets are arranged in series.
    • 化油器包括连接到主喷嘴的主燃料通路和连接到慢端口的缓慢燃料通路。 主燃料路径和慢燃料路径彼此分离,并且独立地连通到低于燃料室的燃料水平面的恒定燃料室。 慢速燃料路径包括位于燃料水平面上方的第一慢喷嘴和位于第一慢喷嘴下游的第二慢喷嘴。 第二慢喷嘴的开口尺寸小于第一慢喷嘴的开口尺寸,并且第一和第二慢喷嘴串联排列。

    • To provide an overflow device for suppressing undue emission of fuel from an overflow pipe which can be produced with a simple structure at a low cost, and can be simply applied also to any existing carburetors. An overflow device for a float type carburetor includes an overflow pipe having an upper end opening exposed to a space in a float chamber defined above a constant fuel level in the float chamber, and a shield member arranged above the constant fuel level for forming a shielded space in the vicinity of the upper end opening. The shield member has a side wall vertically extending above and below the upper end opening, a top wall positioned above the upper end opening, and a bottom wall positioned below the upper end opening. The bottom wall is formed with fuel holes for allowing the fuel to flow into and out of the shielded space. The side wall is formed with small vent holes capable of suppressing the entry of the fuel into the shielded space.
    • 提供一种溢流装置,用于抑制来自可以以简单结构以低成本生产的溢流管的不适当排放的燃料,并且可以简单地应用于任何现有的化油器。 用于浮式化油器的溢流装置包括溢流管,该溢流管具有暴露在浮子室中的空间中的上端开口,该浮子室限定在浮子室中恒定的燃料液位之上,以及屏蔽件,其布置在恒定燃料液位之上,用于形成屏蔽 在上端开口附近的空间。 屏蔽构件具有在上端开口上下垂直延伸的侧壁,位于上端开口上方的顶壁和位于上端开口下方的底壁。 底壁形成有用于允许燃料流入和流出屏蔽空间的燃料孔。 侧壁形成有能够抑制燃料进入屏蔽空间的小通风孔。
