FUEL SYSTEM COMPONENT AND ITS MANUFACTURING PROCESS

PROBLEM TO BE SOLVED: To provide a fuel fill nipple in which a gas barrier passage can be formed between a fuel tank and a fuel supplying pipe and no peeling-off occurs. SOLUTION: A fuel tank is substantially composed of a shell which is impermeable to a fuel vapor but stores a fuel, an opening for...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel fill nipple in which a gas barrier passage can be formed between a fuel tank and a fuel supplying pipe and no peeling-off occurs. SOLUTION: A fuel tank is substantially composed of a shell which is impermeable to a fuel vapor but stores a fuel, an opening for receiving a fuel in the shell and a fuel fill nipple. The fuel fill nipple is equipped with a fuel vapor barrier layer through the opening. The fuel fill nipple is attached to the shell with forming a passage and its passage is coincided to the opening and the fuel can be flown into the tank through the fuel fill nipple. The fuel fill nipple is composed at least of an inner layer for forming an inner surface, an outer layer for forming an outer surface and at least one intermediate layer for forming a barrier layer. The intermediate layer is composed of a material different from the materials in the inner layer and the outerlayer so that passing through of a hydrocarbon can be prevented.
