摘要： A fuel pouring nozzle for use on vented fuel containers has a base adapted to be attached to a vented fuel container. The base has an end portion at a first end, a downstream end at a second end and a radially extending circumferential ridge situated on the end portion. There is a tubular valve body having a cylindrical side wall with an opening therein, an upstream end having a valve seat and a downstream end having a female threaded portion. A tubular conduit is connected to the upstream end of the valve body and the downstream end of the base. A first O-ring is fitted to the valve seat and faces the downstream end of the valve body. A second O-ring is fitted about the opening in the side wall inside the valve body. A ball valve is positioned in the valve body against both O-rings. The ball valve has a stem extending through the opening in the side wall and is rotatable about a longitudinal axis through the stem. There is handle exterior to the valve body and connected to the stem of the ball valve. A tubular member has an upstream end with a male threaded portion engaging the female threaded portion of the valve body, an accordion-like, snap-lock, segmented portion attached to the male threaded portion and a narrowed, rigid tubular section connected to the segmented portion and forming a spout. There is a closure cap having a protrusion on one side which releasably fits with the base to seal the nozzle and has a slot to releasably engage the handle on the ball valve so the cap acts as a knob to open and close the valve.
摘要翻译：用于排放燃料容器的燃料倒出喷嘴具有适于附接到通风燃料容器的底座。底座具有在第一端的端部，位于第二端的下游端和位于端部上的径向延伸的周向脊。有一个管状阀体，其中具有一个开口的圆柱形侧壁，上游端具有一个阀座，一个下游端具有内螺纹部分。管状管道连接到阀体的上游端和底座的下游端。第一个O形圈安装在阀座上并面向阀体的下游端。第二个O形圈安装在阀体内侧壁的开口处。球阀相对于两个O形圈定位在阀体中。球阀具有延伸穿过侧壁中的开口的杆，并且可绕纵向轴线转动通过杆。阀门外部有把手外部，并连接到球阀的阀杆。管状构件具有上游端，其具有接合阀体的阴螺纹部分的外螺纹部分，附接到阳螺纹部分的手风琴状的卡扣锁定分段部分和连接到分段的狭窄的刚性管状部分部分并形成喷口。封闭帽具有一侧上具有可释放地与底座配合的突起，用于密封喷嘴并且具有可释放地接合球阀上的把手的狭槽，因此帽用作旋钮以打开和关闭阀。
