Abstract
Periodic, on-demand supply of heated and pressurized gas for use as a power source is provided by a device having a storage compartment storing pressurized, liquified, combustible gas, a pressure regulator attached thereto for feeding the liquified gas to a housing providing a combustion chamber with an ignition element for combustion of the liquified combustible gas. A pressure relief valve releasably seals the combustion chamber from an outlet orifice and operates at a predetermined gas pressure to permit output of combustion gas from the combustion chamber through the output orifice to provide a gas power source for operating a gas powered tool. A check valve prevents combustion of the liquified gas upstream of the combustion chamber.
