    • A canister to be used in the fuel supplying system of an internal combustion engine of a vehicle, is disclosed. The canister is provided with a fuel vapors guiding pipe for guiding the fuel vapors from a fuel vapors inlet port into a bed of adsorbent material accomodated within a housing, and a deflector for deflecting the flow of fuel vapors guided by the guiding pipe so as to be dispersed throughout the bed. The deflector is formed of air-permeable material having a flowing resistance slightly larger than that of the bed into a frusto-conical plate. According to the present invention, one part of the fuel vapors flowing into the bed through the guiding pipe in the fuel vapors adsorbing process flows along the upper surface of the deflector in the direction of the upper portion of the bed and another part of the fuel vapors flows through the deflector in the direction of the lower portion of the bed. Fresh air sucked into the bed in the fuel vapors purging process flows through the bed without being obstructed by the deflector so that the fuel vapors adsorbed by the whole bed are purged.
    • 公开了一种用于车辆内燃机的燃料供应系统中的罐。 所述罐设置有燃料蒸汽引导管,用于将燃料蒸汽从燃料蒸气入口引导到容纳在壳体内的吸附剂材料床;以及偏转器,用于偏转由引导管引导的燃料蒸气流,以便 分散在整个床上。 偏转器由透气材料形成,其具有比床的流动阻力稍大于截头圆锥形板的流动阻力。 根据本发明,在燃料蒸气吸附工序中通过引导管流入床中的一部分燃料蒸汽沿着上部的方向沿着偏转器的上表面流动,另一部分燃料 蒸汽沿着床的下部的方向流过偏转器。 在燃料蒸气吹扫过程中吸入床中的新鲜空气流过床而不被偏转器阻挡,使得被整个床吸附的燃料蒸气被清除。
