Abstract
In a fuel tank with a filler neck of plastic material which filler neck is connected at one end to the fuel tank and has a filler opening at its other end, a vent pipe extending from the tank to the filler opening, an adsorber chamber with a chamber opening and a fuel vapor conduit providing for communication of the tank with the adsorber chamber are all integrally formed with the filler neck in a single blow molding step, the adsorber chamber, after being filled with a bag of activated carbon, being closed by a lid which carries a regeneration valve and covers the chamber opening.
Claims8
A method of making a fuel tank with a filler neck of plastic material wherein said filer neck is connected at one end to said tank and has a filler opening at its opposite end, a vent pipe extending from the tank to said filler opening, an adsorber cheer with an opening arranged adjacent said filler neck, a fuel vapor conduit extending between the top of said tank and said adsorber chamber and a lid for closing said chamber, said method comprising the steps of:
- blow molding said filler neck from a plastic material so as to form, integrally with said filler neck, said vent pipe, said fuel vapor conduit and said adsorber chamber, inserting a bag with activated carbon into said adsorber chamber and closing said adsorber chamber with said lid.
A fuel tank, particularly for automotive vehicles, having a filler neck of a plastic material, an adsorber chamber receiving activated carbon and being in communication with said fuel tank, a fuel vapor conduit extending from a top area of said tank to said adsorber chamber, said adsorber chamber enclosing a bag including activated carbon and having an opening for inserting said bag, and a lid with a regenerating valve mounted thereon extending across, and closing, said opening so as to contain said bag with activated carbon in said adsorber chamber.
