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.

[ I claim:] [1.] Apparatus for supplying periodic, on-demand, heated and pressurized gas, said apparatus comprising:a storage compartment housing pressurized, liquified, combustible gas and having a liquified gas outlet;a combustion chamber housing defining a combustion chamber, a liquified gas inlet and a combustion gas outlet;means for regulating pressure in fluid communication with the liquified gas outlet for permitting liquified gas of a first predetermined pressure to flow from the storage compartment through the liquified gas outlet to the liquified gas inlet and into the combustion chamber;check valve means for permitting flow of pressurized, liquified, combustible gas into the combustion chamber through the liquified gas inlet but preventing propagation of combustion upstream from the combustion chamber;pressure relief valve means in fluid communication with the combustion gas outlet for permitting release of heated, pressurized gas from the combustion chamber through the combustion gas outlet upon gas pressure in the combustion chamber reaching a second, higher predetermined pressure level and for preventing flow of gas through said combustion gas outlet upon gas pressure in the combustion chamber declining to a pressure at or below the first predetermined pressure; andignition means for initiating combustion of the pressurized, liquified, combustible gas in said combustion chamber.
