ABSTRACT:
A closed pressure housing is provided having an internal partition dividing the interior of the housing into first and second chambers. The first chamber includes a pressurized gas inlet and a liquid fuel reservoir is disposed within and opens into the interior of the first chamber. Fuel supply means is provided for supplying liquid fuel under pressure to the fuel reservoir and structure is operatively associated with the fuel reservoir for heating the latter and vaporizing the liquid fuel therein. A combustion gas transfer passage communicates the first and second chambers and is controlled by a check valve and ignition means is provided within the first chamber for igniting a combustible mixture of pressurized gas and vaporized fuel within the first chamber. Finally, the second chamber includes a combustion gas outlet and the effective flow rate of the combustion gas outlet is less than the effective flow rate of the gas pressure transfer passage. Accordingly, the second chamber acts as a pressure accumulator for modulating pressure pulses discharged through the transfer passage from the first chamber into the second chamber and a reasonably high pressure of combustion gases is maintained within the second chamber, even though the combustion of gas and vaporized fuel within the first chamber occurs intermittently.
