<P>PROBLEM TO BE SOLVED: To provide a fuel pressure vessel, in which dimethyl ether is held as a fuel, made of a resin with excellent chemical-resistance. <P>SOLUTION: When dimethyl ether considered as a substitution for a liquefied petroleum gas is stored, a usually used resin cannot be used by permeability and corrosion even if it is used as such. A vessel is molded using any one of polyamide, i.e., a crystalline resin, polybutyrene terephthalate, polyacetal or polypropylene. A tank part 2 of a gas lighter, i.e., one of the fuel pressure vessel is molded, for example, by polyamide. Dimethyl ether as a fuel is poured into the tank part 2 and is sealed at a body part 3. Upon usage an operation button 4 is pressed to activate a piezoelectric unit 8 and an ignition is carried out to the gas of dimethyl ether injected from an injection nozzle. It can bear to a heat-cycle test and a heat-resistance test and can be effected for practical use. <P>COPYRIGHT: (C)2003,JPO |
