    • PROBLEM TO BE SOLVED: To provide a device capable of supplying fuel to an internal combustion engine while improving a utilization rate of vaporized fuel.SOLUTION: A temporary transition is achieved from a third state (in which a primary recovery path FL1 is closed, a secondary recovery path FL2 is closed, a second vaporized fuel path VL2 is closed, and a condenser 30 is decompressed) to a fourth state (in which the primary recovery path FL1 is closed, the secondary recovery path FL2 is closed, the second vaporized fuel path VL2 is opened, and the condenser 30 is decompressed). Thereby, an internal air pressure P of the condenser 30 is temporarily increased, and the kinetic energy of a vaporized fuel V flowing out of a first fuel tank 40 through the second vaporized fuel path VL2 can sweep away a first fuel F1 in a liquid state accumulated in a vacuum pump 36 to the first fuel tank 40.

    • PURPOSE:To prevent fuel vapor from scattering into the atmosphere, and as well to enhance the power performance of an engine, by disposing a gas separating membrane parting between a fuel vapor introducing space into which fuel vapor from a fuel tank is introduced and an atmospheric space so that condensed fuel is returned into the tank. CONSTITUTION:During rest of an engine fuel vapor generated in fuel tank 1 is introduced into a fuel vapor introduction space 14 in a fuel vapor separating container 3 from a inlet port 4 by way of a vapor passage 2. Then air permeates a gas separating membrane 26 in a gas separating part 12 and enters into an atmospheric space, accompanied with increase in the pressure of the above-mentioned space 14. At this time fuel vapor is inhibited from permeating the gas separating membrane 26, and therefore, is pooled in this space 14. Fuel vapor in the space 14 is finally condensed, and is pooled in a fuel pooling section 18. When the engine is operated so that gas pressure within a gas space in the tank 1 lowers resulting in that a pressure differential across a check valve 8 reaches a predetermined value, the check valve 8 opens so that fuel in a fuel pooling section 18 is returned to the tank 1 through a return passage 5 due to negative pressure of the tank 1.
    • 目的:为了防止燃料蒸汽散逸到大气中,以及提高发动机的动力性能,通过在引入燃料箱的燃料蒸气和燃料蒸汽引入空间的气体分离膜之间设置分离膜, 空间使得冷凝燃料返回到罐中。 构成:在发动机停转期间,燃料箱1中产生的燃料蒸气通过蒸气通道2从入口4引入到燃料蒸气分离容器3中的燃料蒸汽引入空间14中。然后空气渗入气体分离膜 26在气体分离部分12中并进入大气空间,同时伴随着上述空间14的压力的增加。此时,燃料蒸气被阻止渗透气体分离膜26,因此汇集在此 空间14中的燃料蒸气最终被冷凝,并且汇集在燃料池部分18中。当发动机被操作以使得罐1中的气体空间内的气体压力降低时,导致在支架 阀8达到预定值,止回阀8打开,使得燃料池部分18中的燃料由于罐1的负压而通过返回通道5返回到罐1。

    • PURPOSE: To prevent a high boiling point fraction of liquid fuel from sticking to an adsorbing material and thereby to prevent deterioration of the adsorbing material, by providing a separating chamber for separating a vapor phase from a liquid phase in a passage leading from a tank port communicated with a fuel tank to the adsorbing material, and thereby permitting vaporized fuel only to be introduced to the adsorbing material in a canister.
      CONSTITUTION: There is provided a second partition wall 20 connected to a casing 10 at both ends thereof between an opening portion inside of the casing of a tank port 13 of the casing 10 and a first diffusion chamber 12 on an inlet side in a canister. Further, a separator chamber 21 which the tank port 13 is opened into is formed between the second partition wall 20 and the casing 11. The second partition wall 20 is provided with a first passage 22 communicated with the first diffusion chamber 12. Liquid fuel as flown in upon rapid turning of a vehicle is introduced to the separator chamber 21, and vaporized fuel only is adsorbed through the first passage 22 to an adsorbing material 10. Therefore, the adsorbing material 10 is not deteriorated by the liquid fuel.
