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 fuel cutoff valve includes a first float mechanism housed in a first valve chamber of a casing, and a second float mechanism housed in a second valve chamber. During fueling operations, when an intake opening becomes blocked by fuel, the second float mechanism closes second vent holes, and the first float mechanism closes a connecting passage. At times other than fueling operations, when the intake opening becomes blocked by fuel, because the fuel tank interior and the first and second valve chambers, communicate through the second vent holes in addition to the first vent holes, differential pressure between tank internal pressure and pressure of the valve chambers does not rise to the point of actuating the closing operation of the first float mechanism, and the fuel tank FT does not become sealed.

摘要： A fuel cutoff valve 10 has a float assembly 52 and an upper valve plug 60 located in a valve chest 30S defined by a casing 20. The float assembly 52 has a valve support member 55 formed in its upper portion to support the upper valve plug 60. The upper valve plug 60 has a support convex 66b held on a support plane 56a of the valve support member 55, where a center of gravity of the upper valve plug 60 is located below a supporting point 55a around which the support convex 66b is balanced on the valve support member 55. The upper valve plug 60 includes a first valve section 61 and a second valve section 65. The first valve section 61 has a first valve body 62 and a sheet member 64. The first valve body 62 is made of POM (polyoxymethylene), while the second valve section 65 is made of PA6 (polyamide) containing 30% of glass fibers. The second valve section 65 is accordingly structured to have a lower density than the first valve body 62. This arrangement ensures the excellent sealing property even in the event of vibration of the fuel cutoff valve 10 submerged in the liquid fuel by inclination of the vehicle body.

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.
