Abstract
Abstract High-pressure gas generating apparatus includes a combustion chamber and a water jacket surrounding the combustion chamber. A metal fuel injecting nozzle is disposed in the center of one end of the combustion chamber. The water in the jacket is injected into the combustion chamber in the form of a swirling stream around the fuel injected from the nozzle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
An apparatus for generating a high pressure gas comprising a gas generator body including a combustion chamber and a water jacket surrounding the combustion chamber, a metal fuel injecting nozzle disposed in the center of one end of the combustion chamber, the metal fuel injecting nozzle projecting from a closure plate of the gas generator body into the combustion chamber and having a plurality of orifices formed in its front end directed obliquely with respect to the center line extension of the nozzle, and water swirling and injecting means for forcing out water from the jacket in the form of a swirling stream around an injected metal fuel.
Claim 2
Independent Claim
108 words
An apparatus for generating a high pressure gas comprising a gas generator body including a combustion chamber and a water jacket surrounding the combustion chamber, a metal fuel injecting nozzle disposed in the center of one end of the combustion chamber, the metal fuel injecting nozzle projecting from a closure plate of the gas generator body into the combustion chamber and having a plurality of orifices formed in its front end directed obliquely with respect to the center line extension of the nozzle, and water swirling and injecting means for forcing out water from the jacket in the form of a swirling stream around an injected metal fuel.
Claim 3
Dependent Claim
57 words
An apparatus as defined in claim 1 wherein the water swirling and injecting means comprises a plurality of water orifices formed in the inner tube at a predetermined spacing and positioned near the nozzle, the water orifices being directed approximately tangentially of the inner tube, the water jacket communicating with the combustion chamber through the water orifices.
Claim 4
Dependent Claim
88 words
An apparatus as defined in claim 1 wherein the water swirling and injecting means comprises a swirler interposed between the front end outer suface of the nozzle and the inner tube and having a large number of blades inclined with respect to the axis thereof, and a plurality of water injecting orifices are formed in the inner tube and positioned at a predetermined spacing between the swirler and a closure plate of the gas generator body, the water jacket communicating with the combustion chamber through the water orifices.
Claim 5
Independent Claim
69 words
An apparatus for generating a high-pressure gas comprising a gas generator body including a combustion chamber and a water jacket surrounding the combustion chamber and a metal fuel storage chamber connected to the combustion chamber with a closure plate interposed therebetween, the closure plate being provided in its center with a metal fuel injecting nozzle directed toward the combustion chamber and having one end open to the storage chamber.
Claim 6
Independent Claim
69 words
An apparatus for generating a high-pressure gas comprising a gas generator body including a combustion chamber and a water jacket surrounding the combustion chamber and a metal fuel storage chamber connected to the combustion chamber with a closure plate interposed therebetween, the closure plate being provided in its center with a metal fuel injecting nozzle directed toward the combustion chamber and having one end open to the storage chamber.
Claim 7
Dependent Claim
16 words
An apparatus as defined in claim 4 wherein the storage chamber accommodates a fuel pressing piston.
Claim 8
Dependent Claim
34 words
An apparatus as defined in claim 4 wherein a rupture disk for preventing transfer of a metal fuel from the storage chamber to the combustion chamber extends over one end of the storage chamber.
Claim 9
Independent Claim
149 words
An apparatus for generating a high pressure gas comprising a gas generator body including a combustion chamber and a water jacket surrounding the combustion chamber, said gas generator body comprising an inner tube and an outer tube defining the combustion chamber and the jacket, a metal fuel injecting nozzle disposed in the center of one end of the combustion chamber, a closure plate having said metal fuel injecting nozzle, the combustion chamber having an open end serving as a combustion gas outlet, the metal fuel injecting nozzle projecting from a closure plate of the gas generator body into the combustion chamber and having a plurality of orifices formed in its front end directed obliquely with respect to the center line extension of the nozzle, and water swirling and injecting means for forcing out water from the jacket in the form of a swirling stream around an injected metal fuel.
Claim 10
Independent Claim
149 words
An apparatus for generating a high pressure gas comprising a gas generator body including a combustion chamber and a water jacket surrounding the combustion chamber, said gas generator body comprising an inner tube and an outer tube defining the combustion chamber and the jacket, a metal fuel injecting nozzle disposed in the center of one end of the combustion chamber, a closure plate having said metal fuel injecting nozzle, the combustion chamber having an open end serving as a combustion gas outlet, the metal fuel injecting nozzle projecting from a closure plate of the gas generator body into the combustion chamber and having a plurality of orifices formed in its front end directed obliquely with respect to the center line extension of the nozzle, and water swirling and injecting means for forcing out water from the jacket in the form of a swirling stream around an injected metal fuel.
