A coverless fuel device has an elongate housing open at each end and defining first and second longitudinally spaced fluid ports. The first and second door assemblies each include a flapper valve associated with the first fluid port and a second flapper valve associated with the second fluid port, the flapper valves being movable between open and closed positions and being resiliently urged toward their respective closed positions. The pressure relief valve is at least partially contained within the flapper valve. Various plastic components of the coverless device incorporate graphene or graphene derivatives for preventing hydrocarbon emissions from fuel vapors from escaping from the device to the atmosphere.

    一种无盖燃料装置,其具有在每端开口并限定第一和第二纵向间隔的流体端口的细长壳体。第一和第二门组件各自包括与第一流体端口相关联的挡板阀和与第二流体端口相关联的第二挡板阀,所述挡板阀可在打开和关闭位置之间移动并被弹性地推向其各自的关闭位置。泄压阀至少部分地包含在挡板阀的内部。无盖装置的各种塑料部件都并入了石墨烯或石墨烯衍生物,用于阻止来自燃料蒸气的碳氢化合物排放物从装置逸出到大气中。
