Abstract
Abstract A prime source of mechanical power comprising an expansion chamber, an inlet into which expansible fluid is injected, and an outlet through which said fluid is exhausted after expansion in said chamber. Expansion of said fluid is achieved by application of a heat source directly to the expansion chamber, which expansion acts through piston means to create useful mechanical motion. The engine may be of a reciprocating type, rotary or novel turbine, while the heat source can be solar, gaseous, petroleum, nuclear, or electrical. In addition, it is conceived that the novel turbine engine can produce motion by either a rotor driven by a stator or a stator driven by a rotor.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
149 words
A turbine engine comprising: a rotor element; and a juxtaposed stator element surrounding said rotor element, said rotor element including a hub portion provided with at least one nozzle, an annular rim portion having an outer surface containing a series of alternating pockets, and means defining at least one passage in alignment with said nozzle and extending between said hub portion and said rim portion, said passage defining means including heat transfer means, said stator element including an inner surface formed complementally with the outer surface of said rotor element and also containing a series of alternating pockets, said nozzle means being arranged to discharge fluid under pressure into said passage, past said heat transfer means and through said series of alternating pockets in each of said complementally formed surfaces, whereby fluid flow through said nozzle will traverse a tortuous path in divergent directions to drive said rotor element.
Claim 2
Dependent Claim
149 words
A turbine engine comprising: a rotor element; and a juxtaposed stator element surrounding said rotor element, said rotor element including a hub portion provided with at least one nozzle, an annular rim portion having an outer surface containing a series of alternating pockets, and means defining at least one passage in alignment with said nozzle and extending between said hub portion and said rim portion, said passage defining means including heat transfer means, said stator element including an inner surface formed complementally with the outer surface of said rotor element and also containing a series of alternating pockets, said nozzle means being arranged to discharge fluid under pressure into said passage, past said heat transfer means and through said series of alternating pockets in each of said complementally formed surfaces, whereby fluid flow through said nozzle will traverse a tortuous path in divergent directions to drive said rotor element.
Claim 3
Dependent Claim
26 words
A turbine engine as claimed in claim 1, wherein the entire surface area of said surfaces of each of said juxtaposed elements are provided with pockets.
Claim 4
Dependent Claim
21 words
A turbine engine as claimed in claim 1, wherein each of said pockets are formed by circumferentially disposed laterally spaced partitions.
Claim 5
Dependent Claim
26 words
A turbine engine as claimed in claim 3, wherein the partitions in one element are disposed medially of the pockets of the complementally formed adjacent element.
Claim 6
Dependent Claim
22 words
A turbine engine as claimed in claim 1, wherein the pockets are tangentially disposed relative to the surfaces of the juxtaposed elements.
Claim 7
Dependent Claim
50 words
A turbine engine as claimed in claim 1, wherein said passage defining means comprises spaced discs, and wherein said heat transfer means comprises at least one pair of opposed generally radially extending heat convector fins, with each fin of said pair being mounted on a respective one of said discs.
Claim 8
Dependent Claim
76 words
A turbine engine as claimed in claim 1, wherein said passage defining means comprises spaced discs, and wherein said heat transfer means comprises a plurality of pairs of opposed generally radially extending heat convector fins, with each fin of said pairs being mounted on a respective one of said discs, and with adjacent pairs of said fins effecting a division of said passage into a plurality of passage portions each having a nozzle operatively associated therewith.
Claim 9
Dependent Claim
33 words
A turbine engine as claimed in claim 1, wherein said heat transfer means comprises a plurality of heat convector fins connected to said rim portion and extending radially inwardly toward said hub portion.
