Abstract:
A combustion chamber for producing a pressurized gas comprising:a wall structure defining an interior chamber;an explosion chamber disposed within said interior chamber;an annular chamber connected to said explosion chamber;a first reflecting surface for reflecting a pressure wave within said interior chamber;a second reflecting surface for reflecting said pressure wave within said interior chamber, wherein said first and second reflecting surfaces being constructed and arranged to resonate said pressure wave in said interior chamber;at least one first inlet for introducing a first gas into said explosion chamber, said first inlet being located where the pressure in said combustion chamber varies, and said first inlet comprising a first inlet valve for controlling the flow of said first gas into said explosion chamber, said first inlet valve being constructed and arranged to open and close in sync with said resonating pressure wave whereby said first inlet valve is open when lower than average interior chamber pressures are prevalent against said first inlet valve and closed when higher than average interior chamber pressures are prevalent against said first inlet valve;at least one second inlet being located where a pressure varies in said combustion chamber, and said second inlet comprising a second inlet valve for controlling the flow of said second gas into said interior chamber, said second inlet valve being constructed and arranged to open and close in sync with said resonating pressure wave whereby said second inlet valve is open when lower than average interior chamber pressures are prevalent against said second inlet valve and closed when higher than average interior chamber pressures are prevalent against said second inlet valve; andat least one outlet from said interior chamber for drawing off a pressurized gas from said interior chamber, wherein said first inlet valve and said second inlet valve comprise a rotary valve.
