A vent valve assembly for use with a fuel tank may include a housing having an outer wall structure and an inner wall structure defining a chamber therebetween; and a float located within the chamber and configured to be translatable relative to the housing along an axis. The float has an aperture extending along an axis. An inner wall structure of the housing is disposed within the orifice of the float and faces an inner surface of the orifice. The vent valve assembly further includes one or more guide features on the inner surface of the float; and one or more mating guide features on the inner wall structure of the housing and configured to mate with the guide features. The guide feature and the mating guide feature cooperate to guide translation of the float relative to the housing along the axis and limit rotation of the float about the axis.

    一种用于与燃料箱一起使用的排气阀组件,可以包括:壳体,具有外壁结构和内壁结构,在外壁结构和内壁结构之间限定一腔室;以及浮子,位于腔室内并配置为能相对于壳体沿一轴线平移。该浮子具有沿轴线延伸的孔口。壳体的内壁结构设置在浮子的孔口内并面向孔口的内表面。该排气阀组件还包括:一个或多个引导特征部,位于浮子的内表面上;以及一个或多个配合引导特征部,位于壳体的内壁结构上并且配置为与引导特征部配合。引导特征部和配合引导特征部协作,以引导浮子相对于壳体沿轴线的平移并限制浮子围绕轴线的旋转。
