    • In a diaphragm-type carburetor, a fuel vapor treating chamber is provided in a downstream fuel passage which interconnects a fuel pump operated in response to a pulsation pressure from a pulsation pressure generating source and an inlet bore in a constant-pressure fuel chamber. The fuel vapor treating chamber is located before the inlet bore, and a porous element for finely dividing fuel vapor is placed in the fuel vapor treating chamber. Thus, when a fuel vapor is generated in the fuel discharged from the fuel pump, a large amount of fuel vapor can be prevented from being ejected all at one time from a fuel nozzle by finely dividing the fuel vapor and introducing it along with the fuel into the constant-pressure fuel chamber, it is immediately passed toward the fuel nozzle, whereby the variation in air-fuel ratio of a fuel-air mixture can be suppressed to a very small level.
    • 在隔膜式化油器中,燃料蒸汽处理室设置在下游燃料通路中,该燃料通道响应于来自脉动压力发生源的脉动压力而操作的燃料泵和恒压燃料室中的入口孔。 燃料蒸汽处理室位于入口孔之前,并且用于将燃料蒸汽精细分离的多孔元件放置在燃料蒸气处理室中。 因此,当在从燃料泵排出的燃料中产生燃料蒸气时,可以通过细分燃料蒸气并将其与燃料一起引入,从而可以防止大量的燃料蒸气从燃料喷嘴一次全部喷射出来 进入恒压燃料室,立即通向燃料喷嘴,由此燃料 - 空气混合物的空燃比的变化可以被抑制到非常小的水平。

    • A diaphragm-type carburetor includes a fuel well communicating with a lower end of a fuel nozzle, a constant-pressure fuel chamber communicating with the fuel well through an outlet bore, and a fuel pump incorporated in fuel passages defined between an inlet bore of the constant-pressure fuel chamber and a fuel tank. A fuel introduction control valve controls the introduction of fuel into the constant-pressure fuel chamber. The fuel introduction control valve includes a valve seat member which communicates at its lower end with the fuel well through a bypass passage extending above the constant-pressure fuel chamber. Thus, when fuel vapor is introduced into the constant-pressure fuel chamber, it immediately passes towards the fuel nozzle, whereby the extreme reduction in air-fuel ratio of a fuel-air mixture can be avoided.
    • 隔膜式化油器包括与燃料喷嘴的下端良好连通的燃料,通过出口孔与燃料井连通的恒压燃料室,以及燃料通道,燃料通道限定在燃料通道的入口孔之间 恒压燃料室和燃油箱。 燃料引入控制阀控制将燃料引入恒压燃料室。 燃料引入控制阀包括阀座构件,其通过在恒压燃料室上方延伸的旁通通道在其下端与燃料井连通。 因此,当燃料蒸气被引入恒压燃料室时,它立即通向燃料喷嘴,由此可以避免燃料 - 空气混合物的空燃比的极度降低。
