Abstract
Abstract A reaction turbine includes (a) first nozzle means to receive heated fluid for expansion therein to form a two-phase discharge of gas and liquid, (b) a separator rotor having an axis and a rotating surface located in the path of said discharge for supporting a layer of separated liquid on said surface, (c) the rotor having reaction nozzle means to communicate with said layer to receive liquid therefrom for discharge in a direction or directions developing torque acting to rotate the rotor.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
85 words
In a reaction turbine, the combination comprising (a) first nozzle means to receive heated fluid for expansion therein to form a two-phase discharge of gas and liquid, (b) a separator rotor having an axis and a rotating surface located in the path of said discharge for supporting a layer of separated liquid on said surface, (c) the rotor having reaction nozzle means to communicate with said layer to receive liquid therefrom for discharge in a direction or directions developing torque acting to rotate the rotor.
Claim 2
Dependent Claim
85 words
In a reaction turbine, the combination comprising (a) first nozzle means to receive heated fluid for expansion therein to form a two-phase discharge of gas and liquid, (b) a separator rotor having an axis and a rotating surface located in the path of said discharge for supporting a layer of separated liquid on said surface, (c) the rotor having reaction nozzle means to communicate with said layer to receive liquid therefrom for discharge in a direction or directions developing torque acting to rotate the rotor.
Claim 3
Dependent Claim
45 words
The combination of claim 1 wherein the rotor defines passage means communicating with said surface to receive liquid flowing from said layer, the passage means extending generally radially outwardly relative to said axis so that liquid in said passage means is pressurized by centrifugal force.
Claim 4
Dependent Claim
24 words
The combination of claim 2 wherein said reaction nozzle means includes multiple reaction nozzles directed generally tangentially relative to the paths of nozzle rotation.
Claim 5
Dependent Claim
26 words
The combination of claim 2 wherein said passage means includes multiple passages each terminating at one of said reaction nozzles, the passages tapering toward the nozzles.
Claim 6
Dependent Claim
24 words
The combination of claim 4 including means for selectively closing off liquid flow from the nozzles to vary the power output from the rotor.
Claim 7
Dependent Claim
19 words
The combination of claim 4 wherein each passage has an entrance subtending a circularly curved portion of said surface.
Claim 8
Dependent Claim
23 words
The combination of claim 6 wherein the reaction nozzle associated with each passage is angularly offset, about said axis, from said passage entrance.
Claim 9
Dependent Claim
53 words
The combination of claim 1 including a second turbine rotor as defined in (b) and (c) of claim 1, and additional nozzle means to receive heated fluid for expansion therein to form a two-phase gas and liquid discharge onto the rotating surface of the second rotor, the two rotors connected to rotate together.
Claim 10
Dependent Claim
20 words
The combination of claim 8 including ducting to supply liquid discharged from the first rotor to said additional nozzle means.
Claim 11
Dependent Claim
18 words
The combination of claim 9 including a source of additional hot fluid supplied to the additional nozzle means.
Claim 12
Dependent Claim
36 words
The combination of claim 1 wherein said heated fluid consists of a low vapor pressure fluid component which remains liquid, and a high vapor pressure fluid which at least partially vaporizes in said first nozzles means.
Claim 13
Dependent Claim
29 words
The combination of claim 1 including a diffuser ring at the periphery of said rotor, and having ports to diffuse outwardly the liquid discharge from said reaction nozzle means.
Claim 14
Dependent Claim
20 words
The combination of claim 12 including means forming a volute located to receive liquid diffusing outwardly via said diffuser ring.
Claim 15
Dependent Claim
20 words
The combination of claim 1 including structure operatively connected to the rotor to be driven thereby, for supplying useful power.
Claim 16
Dependent Claim
12 words
The combination of claim 14 wherein said structure includes an electrical generator.
Claim 17
Dependent Claim
11 words
The combination of claim 14 wherein said structure includes a pump.
Claim 18
Dependent Claim
11 words
The combination of claim 14 wherein said structure includes a compressor.
Claim 19
Dependent Claim
17 words
The combination of claim 1 including ducting to remove separated gas from the vicinity of the rotor.
Claim 20
Dependent Claim
12 words
The combination of claim 18 including condenser means to condense said gas.
