摘要： An apparatus is for inhibiting fuels from flowing out of fuel tanks, and includes a cover, a breather pipe, an upper case, a lower case, and a floating valve. The upper case is welded to the breather pipe in an airtight manner so as to form a chamber for holding the lower case, in which the floating valve is accommodated, therein. Moreover, the breather pipe is welded to the cover in an airtight manner. The apparatus not only obviates O-rings but also is downsized, because the upper case and the breather pipe are sealed by welding.

摘要： A device includes a housing fixed to an upper wall of a fuel tank, and having a communication opening in communication with a canister, a float valve received within the housing and floating on a fuel, and the float valve moving upward and downward so as to close and open the communication opening, and a tubular member communicating with the housing, and extending downwardly from the housing into the interior of the fuel tank. The device has through holes of a small diameter which are disposed near an upper wall of the fuel tank, and when the liquid level of the fuel in the fuel tank reaches the lower end opening of the tubular member, a pressure within the fuel tank increases, whereby the filling-up of the fuel tank is detected. When the liquid level of the fuel abnormally rises, the float valve closes the communication opening.

摘要： A fuel cutoff valve comprises a casing and a float mechanism having a float and a seat portion. An upper vent hole is formed in the upper wall portion of the float, and a side portion communication hole is formed in the side wall portion. The passage area of the side portion communication hole is set so as to allow a large volume of vapors entering the float chamber to escape into the valve chamber. The passage area of the upper vent hole is set so that vapor entering the float chamber when the vehicle inclines escapes into the valve chamber, and the float chamber fills with fuel lifting the float, whereas when the vehicle turns sharply, the float is lifted without the float chamber filling with fuel.

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： 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.

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.
