摘要： The fuel cutoff valve comprises a valve support on the upper part of the float, and the seat member is mounted on the valve support. The valve support has the bending space that has an inner diameter larger than the outer diameter of the seal part. The seat member is formed from a rubber material, has a side wall formed in a cylindrical shape from the outer periphery of the seat part and a stopper on the side wall, forming the mounting space by being formed in an almost a rectangle shape cross section, and being supported on the valve support by fitting the valve support on the mounting space. The seat part is elastically deformed in the bending space direction when set on the seal part and closes the connection path.

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 vent valve is not shut improperly by the flow of fuel vapor. The fuel vent valve also prevents fuel from spilling out from filler neck during filling of a fuel tank. The fuel vent valve includes a casing having a vent space, a float and a vent device which can be moved up and down. The vent device includes an upper valve member, which shuts and opens a communication passage. The upper valve member is located above the float. A breathing hole and an outer wall of the valve device form a restricted passage. When the fuel level reaches a first predetermined level and the valve device rises, the restricted passage increases the flow resistance to restrict the flow of fuel vapor from the communication passage to the outside of the fuel tank. When fuel level reaches a second predetermined level and the valve device rises further, the upper valve member closes the communication passage.

摘要： Provided is a fuel cutoff valve that reduces the emission of fuel vapors from within fuel tanks. The fuel cutoff valve is mounted by partial insertion into a fixation hole provided in an upper tank wall of a fuel tank. The fuel cutoff valve comprises a cover, a casing, a float, and a spring. In the cover, a matrix of polyacetal having excellent resistance to fuel permeation reduces emission of fuel vapors into the atmosphere, while a dispersed phase of polyethylene in the matrix allows welding to fuel tank.
