The invention provides a novel combination valve for an automobile oil tank. The novel combination valve for the automobile oil tank is internally provided with a liquid accumulation cavity, preventsfuel oil liquid from dynamically leaking into a carbon tank, is compact in appearance and high in applicability, integrates the functions of a liquid level control valve and a rollover valve, reducesholes in the oil tank, reduces emission and reduces pipeline connection between the valves. The novel combination valve comprises a liquid accumulation cavity plate, an upper shell and a valve body shell, a main exhaust hole and a second exhaust hole are formed in the surface area of the liquid accumulation cavity plate and penetrate through the liquid accumulation cavity plate in the thickness direction, the upper shell is packaged on the upper portion of the liquid accumulation cavity plate, the valve body shell is packaged at the bottom of the liquid accumulation cavity plate, a liquid level closing valve cavity is formed in the area, corresponding to the lower portion of the main exhaust hole, of the valve body shell, an exhaust valve cavity is formed in the area, corresponding to thelower portion of the second exhaust hole, of the valve body shell, and a laterally-protruding air outlet is formed in the upper shell.

    本发明提供了一种用于汽车油箱上的新型组合阀,其内置积液腔,防止燃油液体动态泄露进入碳罐,且外形紧凑、适用性强,其集成了液位控制阀和翻车阀功能,减少了油箱上的开孔降低排放且减少了阀之间的管路连接。其包括积液腔板、上壳体、阀体外壳,所述积液腔板的面域上设置有主排气孔、第二排气孔,所述主排气孔、第二排气孔分别贯穿所述积液腔板的厚度方向设置,所述积液腔板的上部封装有所述上壳体,所述积液腔板的底部封装有所述阀体外壳,所述阀体外壳对应于所述主排气孔的下部区域形成液位关闭阀腔体,所述阀体外壳对应于所述第二排气孔的下部区域形成排气阀腔体,所述上壳体设置有侧凸的出气口。
