Abstract
A gas fueled lighter having a cylindrical body with a central bore forming a gas passage and a valve port. A check valve blocks flow from a reservoir to the passage, and contains a metering plug to pass gas to the passage. A valve plug threaded and sealed in the bore opens and closes the valve port. Such plug carries a turnknob head, contains a burner port from the gas passage, and carries a flame shield which supports a striker wheel. A flint is pressed against the wheel by a spring supported by a retainer plate on the valve plug. A cap threaded onto the body over the head has threads with the same lead as the valve plug threads so that if the cap is screwed onto the body when the valve is open, the cap will drivingly rotate the valve plug to closed position. A bottom flange on the cap and an O-ring in the body form a secondary seal to prevent fuel leakage and exclude dirt and moisture. The reservoir is filled by removing the valve plug and inserting a fill nozzle into the valve bore and against the check valve. In a modification, gas metering flow through the check valve is adjustably controlled by a rod screwed into the valve.
