ABSTRACT:
The fuel delivery system disclosed herein operates to deliver gaseous fuel to the burner of a hand-held, liquid fueled cigarette lighter from a reservoir of volatile liquid fuel. The system employs a vaporizing chamber communicating with the burner and extending into the reservoir which defines a passage for passing fuel into the vaporizing chamber. A valve, positioned on a valve seat in the passage, comprises an anchoring portion, a poppet nested on the valve seat, and one or more resilient arms integral with the anchoring portion and extending to the poppet for urging the poppet toward the valve seat. The system isolates the pressurized liquid fuel in the reservoir until the biasing force of the valve together with the pressure in the vaporizing chamber is insufficient to hold the poppet in the closed position. Thus, a reduced pressure environment is maintained in the vaporizing chamber which ensures that all the fuel in the chamber will vaporize before passing to the burner.
