Abstract

Abstract A method and apparatus for generating power in response of a fluid flowing from a higher pressure to a lower pressure through a reaction turbine. Said fluid enters said turbine rotor wheel near the center, is then pressurized within said rotor wheel and then discharged via exit nozzles mounted on said wheel in a backward direction; said fluid discharge generating a torque on said wheel, said torque then being passed to the rotor shaft as the useful work output of said turbine. Fluids used may either gaseous, liquids or mixtures of the two.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 384 words
A device for generating power responsive to flow of fluid therethrough comprising: a. a power shaft journalled for rotation in a suitable support for transmission of power; b. a rotating compressing centrifuge rotor carried on said shaft for generating said power; said compressing centrifuge rotor including: i. an inlet port disposed adjacent the center of said compressing centrifuge rotor for entrance of a fluid thereinto; ii. a plurality of interior vanes defining passageways therebetween; said passageways diverging as they traverse radially outwardly of said rotor and communicating with said inlet port and having at any radius a first, large cross sectional area and having disposed at the peripheral portion thereof respective obstructions to the flow of fluid to ensure that said fluid flowed into said compressing centrifuge rotor is moved outwardly at a low radial velocity component and attains the same rotational speed as said compressing centrifuge rotor so as to be subjected to a centrifugal force field sufficient to elevate its pressure to form a high pressure fluid at the peripheral portion of said centrifuge rotor; iii. a plurality of reaction nozzles disposed at the radially outermost portion of said passageways with at least one reaction nozzle communicating with each said passageway; each said reaction nozzle having a second cross sectional area less than said first cross sectional area of its said passageway to ensure that said fluid is compressed by compressing centrifuge action at the operational high rotational speeds of said compressing centrifuge rotor; said reaction nozzles being disposed tangentially of said compressing centrifuge rotor and in a direction opposite the direction of rotation of said rotor so as to direct the effluent fluid tangentially of said compressing centrifuge rotor for developing torque and power that is proportional to a reaction force to the force effecting the velocity difference between the tangential velocity of the effluent fluid and the tangential velocity of said reaction nozzles and, consequently, said compressing centrifuge rotor; said rotor having heavy duty construction sufficient to withstand high rotational speeds; c. a casing sealingly surrounding said compressing centrifuge rotor; said casing defining a passageway surrounding said compressing centrifuge rotor for collection of said effluent fluid; and having respective inlet and outlet passageways; and d. bearing means and seal means disposed intermediate and sealingly engaging said shaft and said casing.
Claim 2
Independent Claim 384 words
A device for generating power responsive to flow of fluid therethrough comprising: a. a power shaft journalled for rotation in a suitable support for transmission of power; b. a rotating compressing centrifuge rotor carried on said shaft for generating said power; said compressing centrifuge rotor including: i. an inlet port disposed adjacent the center of said compressing centrifuge rotor for entrance of a fluid thereinto; ii. a plurality of interior vanes defining passageways therebetween; said passageways diverging as they traverse radially outwardly of said rotor and communicating with said inlet port and having at any radius a first, large cross sectional area and having disposed at the peripheral portion thereof respective obstructions to the flow of fluid to ensure that said fluid flowed into said compressing centrifuge rotor is moved outwardly at a low radial velocity component and attains the same rotational speed as said compressing centrifuge rotor so as to be subjected to a centrifugal force field sufficient to elevate its pressure to form a high pressure fluid at the peripheral portion of said centrifuge rotor; iii. a plurality of reaction nozzles disposed at the radially outermost portion of said passageways with at least one reaction nozzle communicating with each said passageway; each said reaction nozzle having a second cross sectional area less than said first cross sectional area of its said passageway to ensure that said fluid is compressed by compressing centrifuge action at the operational high rotational speeds of said compressing centrifuge rotor; said reaction nozzles being disposed tangentially of said compressing centrifuge rotor and in a direction opposite the direction of rotation of said rotor so as to direct the effluent fluid tangentially of said compressing centrifuge rotor for developing torque and power that is proportional to a reaction force to the force effecting the velocity difference between the tangential velocity of the effluent fluid and the tangential velocity of said reaction nozzles and, consequently, said compressing centrifuge rotor; said rotor having heavy duty construction sufficient to withstand high rotational speeds; c. a casing sealingly surrounding said compressing centrifuge rotor; said casing defining a passageway surrounding said compressing centrifuge rotor for collection of said effluent fluid; and having respective inlet and outlet passageways; and d. bearing means and seal means disposed intermediate and sealingly engaging said shaft and said casing.
Claim 3
Dependent Claim 49 words
The device of claim 1 wherein said casing closely and conformingly receives the ends of said centrifuge rotor such that the high rotational speed of said compressing centrifuge rotor partially evacuates the space between said ends and said casing and effects a reduced friction at operational high rotational speeds.
Claim 4
Dependent Claim 34 words
The deVice of claim 1 wherein said reaction nozzles are at least converging and are sized and shaped to provide for the highest attainable exit velocity of said effluent fluid from said reaction nozzles.
Claim 5
Dependent Claim 19 words
The device of claim 3 wherein said reaction nozzles are converging-diverging for effecting isentropic expansion of said effluent fluid.
Claim 6
Dependent Claim 27 words
The device of claim 1 wherein said fluid is a gas having a high specific heat value at constant pressure, and is being flowed through said device.
Claim 7
Independent Claim 144 words
A method of generating power in response to flow of a fluid through a device wherein a power delivery shaft is connected with a centrifuge rotor comprising the steps of: a. flowing said fluid into said centrifuge rotor and while within the confines of said rotor subjecting said fluid to a centrifugal force field via compressing centrifuge action with low radial velocity component to effect a high pressure fluid at the peripheral portion of said rotor; and b. passing said high pressure fluid out of reaction nozzles that are oriented tangentially and rearwardly from the direction of rotation of the periphery of said compressing centrifuge rotor to provide a tangential reaction force to the periphery of said rotor such that a reaction force to said fluid being passed out of said reaction nozzles is imparted to said rotor to deliver power to said shaft.
Claim 8
Independent Claim 144 words
A method of generating power in response to flow of a fluid through a device wherein a power delivery shaft is connected with a centrifuge rotor comprising the steps of: a. flowing said fluid into said centrifuge rotor and while within the confines of said rotor subjecting said fluid to a centrifugal force field via compressing centrifuge action with low radial velocity component to effect a high pressure fluid at the peripheral portion of said rotor; and b. passing said high pressure fluid out of reaction nozzles that are oriented tangentially and rearwardly from the direction of rotation of the periphery of said compressing centrifuge rotor to provide a tangential reaction force to the periphery of said rotor such that a reaction force to said fluid being passed out of said reaction nozzles is imparted to said rotor to deliver power to said shaft.
Claim 9
Dependent Claim 30 words
The method of claim 6 wherein said high pressure fluid is expanded isentropically as it is flowed out of said reaction nozzles for a greater velocity and greater reaction force.
