<p>The torch or oil lamp burns vapor from entire flame source and provides essentially large flame. Fluid flows down through a filling hole into a container, through a counter valve and a filling device with a safety valve. The arrangement is easier for users and cleaner than with known torches and oil lamps. The safety valve operates via a magnet and a magnetic ball and closes when the torch is tilted downwards for too long counter to the horizontal, as this tends to prevent discharge of combustible fuel.</p> |
