摘要： In a fuel vapor processing device for transferring fuel vapor from a fuel tank to a canister when fuel is fed into the fuel tank through a fuel fill pipe or when the pressure in the fuel tank is raised to a predetermined value, a pressure given through the fuel fill pipe is applied to one side of a first diaphragm valve body forming a first diaphragm valve while a pressure given through a fuel tank passageway is applied to the other side thereof, so that, when the pressure in the fuel tank passageway is increased while fuel is being supplied into the fuel tank, a first communicating hole is opened; and the atmospheric pressure is applied to one side of a second diaphragm valve body forming a second diaphragm valve while a pressure given through the fuel tank passageway is applied to the other side, so that when the pressure in the fuel tank becomes higher than the atmospheric pressure by a predetermined value a second communicating hole is opened. Thus, in both cases, the fuel vapor formed in the fuel tank is moved to the canister.
摘要翻译：在燃料蒸汽处理装置中，当燃料通过燃料填充管供给到燃料箱中时或当燃料箱中的压力升高到预定值时，将燃料蒸汽从燃料箱传送到罐，通过燃料填充管被施加到形成第一隔膜阀的第一隔膜阀体的一侧，同时通过燃料箱通道施加的压力被施加到另一侧，使得当燃料箱通道中的压力增加同时燃料被供给到燃料箱中，打开第一连通孔; 并且大气压被施加到形成第二隔膜阀的第二隔膜阀体的一侧，同时通过燃料箱通道施加的压力被施加到另一侧，使得当燃料箱中的压力变得高于大气压打开预定值的第二连通孔的压力。因此，在这两种情况下，形成在燃料箱中的燃料蒸气被移动到罐。

摘要： A cap with valve for positive pressure comprises a cap body installed to an aperture of a container such as a fuel tank or a radiator of an automobile, a partition wall formed within the cap body and extending from an inner circumferential surface in radial direction and having a first fluid flowing hole, and a valve for positive pressure disposed at upper side of the partition wall. A support plate is disposed at lower side of the partition wall within the cap body and provided with a second fluid flowing hole, and an auxiliary valve chamber is formed between the partition wall and the support plate. Within the auxiliary valve chamber, a stopper valve having specific gravity larger than that of liquid within the container and a float having specific gravity of the combined body with the stopper valve smaller than that of the liquid within the container are arranged at lower side of the first fluid flowing hole and movable up and down. When the container is reversed in upper and lower positions, the stopper valve is moved by own weight towards the partition wall thereby the first fluid flowing hole is closed. Also when the liquid level within the container rises, both the stopper valve and the float are floated, and the first fluid flowing hole is closed by the stopper valve. Consequently, the liquid within the container is prevented from passing through the first fluid flowing hole and flowing out of the container.
摘要翻译：具有正压阀的盖包括安装到诸如燃料箱或汽车散热器的容器的孔的盖体，形成在盖体内并且从径向方向的内周面延伸的隔壁，并且具有第一流体流通孔和设置在分隔壁上侧的正压阀。支撑板设置在盖体内的分隔壁的下侧，并且设置有第二流体流动孔，并且在分隔壁和支撑板之间形成辅助阀室。在辅助阀室内，具有比容器内的液体重的比重的止动阀和具有与止动阀的比重小于容器内的液体的组合体的比重的浮子布置在第一流体流动孔，上下移动。当容器在上部和下部位置反转时，止动阀通过自重移动到分隔壁，从而第一流体流动孔闭合。此外，当容器内的液面上升时，止动阀和浮子都浮起，第一流体流通孔被止动阀封闭。因此，防止容器内的液体通过第一流体流动孔并流出容器。

摘要： A liquid fuel storage device is provided for use with an automobile system including an engine, a fuel tank, and a canister for absorbing fuel vapor during refueling. The device includes an air bag disposed in the fuel tank and constructed and arranged to inflate to occupy a space in the fuel tank in accordance with an amount fuel remaining in the fuel tank. Piping structure communicates the fuel tank with the engine for inflating the air bag by reducing pressure in the fuel tank when the engine is started. An air introduction pipe communicates with the atmosphere and includes a first valve mechanism for introducing air into the air bag and prevents air from escaping from the air bag after inflation thereof. An air emission pipe includes a second valve mechanism, which is opened only in refueling to emit air in the air bag during refueling. The air emission pipe is connected to the canister.

摘要： An evaporation loss control device provided with a polymer chamber filled with polymer absorbent, a charcoal chamber filled with charcoal, introduction and purging pipes for connecting the polymer chamber with a fuel tank and an engine intake passage, respectively, an air pipe for ventilation connected to the charcoal chamber, and a vapor passage, which has various forms. For example, the vapor passage may be formed in spiral to encircle the polymer chamber, or provided between the polymer and charcoal chambers, thus allowing the evaporated fuel to pass therethrough. The vapor passage is constructed to prevent the evaporated fuel trapped by the polymer absorbent from flowing into the charcoal chamber, and also to prevent the liquid fuel from being absorbed by the charcoal.
