    • A primer for an internal combustion engine carburetor including a variable volume air chamber which is provided with a flexible resilient dome member. The dome member includes a protruding nipple including an aperture therein for admitting air into the chamber. Inside the chamber, a protrusion is provided including a sloping surface with an aperture therein. A passage connects the aperture in the sloping surface to the fuel supply bowl. When an operator abruptly depresses the flexible resilient dome member, a volume of air is abruptly displaced from the chamber through the passage and into the fuel supply bowl to force fuel from the bowl through a nozzle and into a fuel/air mixture passageway of the carburetor.
    • 一种用于内燃机化油器的底漆,其包括设置有柔性弹性圆顶构件的可变体积空气室。 圆顶构件包括突出的接头,其中包括用于将空气引入腔室的孔。 在室内设置有包括其中具有孔的倾斜表面的突起。 通道将倾斜表面中的孔连接到燃料供应碗。 当操作者突然压下柔性弹性圆顶构件时,一定量的空气从腔室突然移出通过通道并进入燃料供应碗中,以迫使来自碗的燃料通过喷嘴并进入化油器的燃料/空气混合物通道 。

    • A carburetor prevents priming of a combustion engine under certain operating conditions. The carburetor includes a body member having a wall portion defining an orifice extending through the body member, a fuel nozzle positioned through the wall portion and in operative communication with the orifice, a fuel bowl positioned in operative communication with the fuel nozzle, a primer device in operative communication with the fuel bowl, and a primer lockout operatively positioned between the primer device and the fuel bowl. A method of controlling the carburetor during start-up and warm-up of a combustion engine is also described, including the steps of actuating the primer device to prime the carburetor, starting the engine with the external vent in open communication with the fuel bowl, disabling the primer device when the engine reaches a first operating temperature, and closing the external vent when the engine reaches a second operating temperature.
    • 化油器防止在某些操作条件下起动内燃机。 化油器包括主体构件,其具有限定延伸穿过主体构件的孔口的壁部分,通过壁部分定位并与孔口可操作地连通的燃料喷嘴,与燃料喷嘴可操作地连通的燃料碗,底漆装置 与燃料碗操作连通,以及可操作地定位在底漆装置和燃料碗之间的底漆锁定。 还描述了一种在内燃机起动和预热期间控制化油器的方法,其包括以下步骤:启动底漆装置以引燃化油器,起动发动机,其中外部通风口与燃料碗开放连通, 当发动机达到第一工作温度时禁用底漆装置,并且当发动机达到第二工作温度时关闭外部排气口。
