摘要： A fuel cutoff valve includes a full fuel control valve and an overfill prevention valve inside a casing. The overfill prevention valve is equipped with first and second floats. The second float is disposed in the storage chamber inside the first float of the full fuel control valve while being allowed to move up and down. The second float is configured such that a second connection conduit is closed by a second valve element as a result of a rising movement when the fuel level exceeds a second liquid level located above a first liquid level, and the second valve element is connected to a first connection conduit through a second connection conduit to reduce the force with which the first valve element of the first float is pressed against a first seat as a result of the fact that the fuel level has dropped below the second liquid level but is still above the first liquid level.

摘要： A fuel cutoff valve is mounted on an upper wall of a fuel tank to open and close a connection conduit, so as to connect and disconnect the fuel tank with and from outside. The fuel cutoff valve of the present invention includes a casing, a cup-shaped float, a bottom plate, and a cover. Both the cover and the casing swell in the liquid fuel. The cover is made of a first resin material, which has the greater fuel swelling property than a second resin material that is applied for the casing. The cover is accordingly expanded to a greater degree than the casing. A holder unit disposed on the casing increases the supporting force against a support member of the cover with the swell of the cover. The casing is thus securely held by the cover via the holder unit and is not movable against the cover under the swelling condition of the cover. The fuel cutoff valve of the present invention accordingly attains the stable valve opening and closing properties without any possible troubles due to the unsteady joint, for example, a lowered mechanical strength against shocks or a variation in opening and closing liquid levels of the fuel cutoff valve.
摘要翻译：燃料切断阀安装在燃料箱的上壁上，以打开和关闭连接导管，从而将燃料箱与外部连接和断开。本发明的燃料截止阀包括壳体，杯形浮子，底板和盖。盖子和套管在液体燃料中膨胀。该盖由第一树脂材料制成，其具有比应用于壳体的第二树脂材料更大的燃料膨胀性能。相应地，该盖膨胀到比套管更大的程度。设置在壳体上的保持器单元随着盖的膨胀而增加抵靠盖的支撑构件的支撑力。壳体因此通过保持器单元被盖牢固地保持，并且在盖的膨胀状态下不能抵靠盖移动。因此，本发明的燃料切断阀达到稳定的开阀和关闭性能，而不会由于不稳定的接头而引起任何可能的麻烦，例如降低了对冲击的机械强度或燃油切断阀的开启和关闭液位的变化。

摘要： Disclosed is a valve being attached to a fuel tank, the valve permitting a vaporized fuel to flow out and inhibiting a liquid fuel from flowing out. The valve includes a cover and a case. For example, the cover is bonded to an upper portion of a fuel tank, is independent of the fuel tank, and includes a connecting surface to be connected to the fuel tank and a flow-out passage in which a vaporized fuel flows out. The connecting surface has a connector portion formed of a resin exhibiting a good bondability to the fuel tank. The case is screwed to the cover, and includes an evaporator opening and a floating valve. The evaporator opening communicates with the flow-out passage. The floating valve opens or closes the evaporator opening.

摘要： A welding joint 10 for a fuel tank reduces the amount of fuel vapor in the fuel tank that escapes into the atmosphere. The fuel tank welding joint 10 a joint main body 20 and a barrier layer laminated on the surface of the joint main body 20. The joint main body 20 is formed of a first resin material weldable to the wall of the fuel tank FT, and the barrier layer 30 is formed of a second resin material that is adhesively and chemically reactive with the first resin material and that is more fuel-impermeable than the first resin material. An end portion 34 formed so as to be exposed to the outside at the end of a tube portion 24 is formed on the barrier layer 30. When the barrier layer 30 is injection molded on the surface of the joint main body 20, the end portion 34 is formed by the flow of the second resin material through the end of the tube portion 24 to increase the adhesive strength of the end face where the parts are joined.

摘要： A fuel shut-off valve includes a casing, an ascendable and descendible float, and an upper valve element, which is actuated by the float to open and close connector passage that communicates the inside of fuel tank with the outside, and which includes a valve body and a ring-shaped seat member. The ring-shaped seat member makes a connector bore, which communicates with the connector passage, therein, and includes a base, a holding portion, a seating portion, a lip-shaped portion, and a thin-film-shaped portion. The seating portion opens and closes the connector passage, and defines an opening of the connector bore. The lip-shaped portion seats on and separates away from the float, and defines the other opening of the connector bore. The thin-film-shaped portion is disposed between the base and the lip-shaped portion, and is deformable elastically upon being pressed by the float when the float seats on the lip-shaped portion.

摘要： A float valve for use in a fuel tank, having a float for regulating air flow out of an air outflow channel provided in an upper portion of the fuel tank. An air flow deflecting portion provided on the float prevents the float from being lifted as air and fuel vapors displaced when the fuel tank is filled-up escape the tank. When the fuel level in the tank rises to a filled-up position, the outflow of air is stopped by the float.
