(Cl. 60--39.S2) carbon dioxide, after being cooled in the coolant chamber 21, is directed by means of conduit 23 into a compressor 24 connected by shaft 25 to the turbine wheel 17 and the compressed gases are then directed into the chamber 10. The chemical reaction taking place in the chambers 10 This invention relates to a power system and more par ticularly to a closed circuit system for generating power. and 12 can be shown as follows: It is the general object of this invention to produce a 10 al ( 2x02 + oo. _» Krom-igor + Hear new and improved power generator of the character de scribed. b It is a more specific object of the present invention to O Ca2+-3502 _» col-l-nzo-x-Heat produce a power system which may utilize a hydrocarbon fuel without the necessity of provisions for exhaust and 15 The reaction a takes place within the reaction chamber providing for the re-use of certain elements of combustion 10 and the reaction b takes place in the combustion cham to provide -a self-sustaining reaction. ber 12. The cooling which takes place in the coolant As will be clear to those skilled in the art from the chamber 21 may be effected by sea water carried through description which follows, the present invention provides suitable tubes (not shown) and entering the chamber 20 for a power generating system utilizing a closed circuit through the inlet indicated -at 26 and exiting through the and eliminating the necessity for an exhaust discharge. outlet indicated at 27. ` This being the case, the power generating system of the A somewhat similar arrangement is shown in FIG. 2 present invention is particularly useful under circum wherein there is illustrated a reaction chamber 30 con stances where the supply of oxygen for combustion may nected by a line 31 to a combustion chamber 32. A fuel Ibe limited or where it is undesirable to provide for ex haust. A particularly useful application of the present 25 line 33 is connected to a fuel chamber 34 and serves to introduce hydrocarbon fuel into the combustion chamber invention is in a »drive for a submarine or a submarine 32. The gases resulting from the combustion are directed by conduit 36 into a boiler 37.

Within the chamber Other and further objects of the invention will be read is located the perforate pipe 49 allowing the gases to ily apparent from the following description taken in con 40 permeate through the KO2 indicated at 50 which fills the torpedo. The power generating system of the present in nection with the accompanying drawings, in which: chamber 30 and surrounds the perforate pipe 49. The reaction taking place in the reaction chamber 30` is the FIG. l is a diagrammatic view of a submarine motor employing the principles of the invention; and FIG. 2 is a view like FIG. l of a modified form of the invention. While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail two embodiments, with the understanding that the present disclosure is to be con same as that occurring in the chamber lil and the com bustion in the combustion chamber 32 serves the same 45 purpose as the combustion in chamber 12. Water from the reaction in the combustion chamber condensing in the boiler 37 is directed by means of line 51 and pump 52 into the fuel chamber 34 to replace the fuel expended therefrom. sidered as an exemplification of the principles of the in 50 It will be noted from the foregoing description that the vention and is not intended to limit the invention to the embodiments illustrated. The scope of the invention will circuit can be closed in that no exhaust is necessary. The absence o-f the requirements for an exhaust render the be pointed out in the appended claims. Referring now to FIG. 1 of the drawings, there is shown a reaction chamber 10 containing a suitable chem ical such as potassium oxide (KOZ) capable of absorbing at least one of the products of combustion and giving off oxygen. The reaction chamber 10 is connected by means of conduit 11 to a combustion chamber 12. system particularly adaptable for use Where the presence of exhaust is undesired such as for deep running torpedos. 55 I claim: l. A power generating system comprising a fuel charn ber adapted to contain a hydrocarbon fuel, a reaction chamber and a combustion chamber, means in the re Also con action chamber to produce oxygen from carbon dioxide, nected to the combustion chamber 12 through line 13 is 60 means for directing such oxygen and fuel into the com a fuel chamber 14 and fuel is delivered through the line bustion chamber to combine therein to produce carbon 13 by means of the pump 15. The fuel in chamber 14 dioxide and water vapor, means for utilizing the energy may be a hydrocarbon fuel which when combined with of combustion to generate power, a coolant chamber for oxygen in the combustion chamber 12 produces the usual cooling the products of combustion and to condense the products of combustion, namely, carbon dioxide, water 65 water therein, means for directing the carbon dioxide into and heat.
