摘要： A canister for adsorption of evaporated fuel in an automobile. The canister operates to decrease leakage of the evaporated fuel when the atmosphere temperature rises or the canister is left as it is for a long time. To this end, the canister according to the invention comprises a first container provided in adjacent to an inlet for evaporated fuel and incorporating therein a liquid-phase component adsorbent, a second container provided on the downstream of the first container and on the side or the top of the first container and filled with an adsorbent, and a third container disposed between the second container and an atmosphere port and filled with an adsorbent. Further, the first, second and third container are integrally formed. With such structure, liquid-phase components of the evaporated fuel are collected by the adsorbent in the first container so that a life span of the adsorbent in the second container can be elongated. Further, since the third container is filled with the adsorbent, the evaporated fuel forcibly discharged from the adsorbent of the second container is collected by the adsorbent in the third container when the atmosphere temperature rises or the canister is left for a long time. Therefore, the evaporated fuel can be prevented from being discharged into the atmosphere.
摘要翻译：用于吸附汽车中蒸发燃料的罐。当大气温度升高或者罐长时间放置时，罐可以减少蒸发燃料的泄漏。为此，根据本发明的罐包括与蒸发燃料的入口相邻设置的第一容器，并且在其中并入有液相成分吸附剂，第二容器设置在第一容器的下游侧，第一容器的顶部并填充吸附剂，以及设置在第二容器和大气口之间并填充有吸附剂的第三容器。此外，第一，第二和第三容器是一体形成的。通过这样的结构，蒸发的燃料的液相成分被第一容器中的吸附剂收集，使得第二容器中的吸附剂的使用寿命可以延长。此外，由于第三容器填充有吸附剂，当大气温度升高或者长时间放置罐时，由第三容器中的吸附剂将从第二容器的吸附剂强制排出的蒸发燃料收集。因此，可以防止蒸发的燃料排放到大气中。

摘要： An apparatus is provided for preventing emission of fuel vapor generated in a fuel tank during fuel supply, including a fuel supplying canister for absorbing the fuel vapor and desorbing the absorbed fuel vapor by an intake air flow in the operation of an internal combustion engine. The fuel supplying canister is provided, on one side of its vessel, with a tank port connected to the fuel tank and a purge port connected to an air intake passage of the internal combustion engine, and also provided with an atmospheric air port for introducing air on the other side thereof. The atmospheric air port includes a switching device for controlling the cross-sectional area of an atmospheric air passage in a manner that the switching device is fully opened during fuel supply, and that at other times a predetermined restriction hole is defined therein. Owing to this structure, the intake pipe negative pressure in the internal combustion engine can be efficiently applied into the canister without degrading the fuel supplying efficiency, so that the desorption of the fuel vapor absorbed in the activated carbon of the canister during fuel supply is much improved. Moreover, the residual fuel vapor in the activated carbon becomes less, and consequently, the lowering or degradation of absorption efficiency of the activated carbon because of aged deterioration can be prevented.

摘要： A system for preventing loss of fuel due to evaporation in internal combustion engine, particularly in automotive engine. The system has a casing accommodating a fuel gas absorbent. A separator chamber adapted to separate the liquid phase and gaseous phase of the fuel from each other is disposed in a passage through which a tank port leading from a fuel tank is communicated with the absorbent. The passage is so constructed as to permit only the gaseous phase of the fuel to be sent to the absorbent.
