Patent ID: 8567176

Claim:
A rotating device for producing a pressure of a fluid by expansion, comprising: a U-channel structure ( 120 ) extending radially from an axis of rotation of a shaft ( 121 , 122 ), wherein the rotating device is fitted within an anchored housing ( 413 ) with bearings rotatably coupling the shaft ( 121 , 122 ) to the housing ( 413 ), and wherein the U-channel structure includes an expansion point ( 105 ) arranged at a periphery of the rotating device, a sink channel ( 104 ) for supplying a pressurized fluid to said expansion point ( 105 ), a propellant channel that follows a contour of the sink channel and provides a propellant fluid to the expansion point, and a rise channel ( 107 ) for supplying an expanded fluid from said expansion point ( 105 ) through an outlet channel ( 112 ) to a regulation valve ( 110 ) to supply said expanded fluid at a higher pressure than that of the pressurized fluid to an energy utilization device, and wherein the sink channel and the rise channel are connected to one another at the expansion point where the pressurized fluid is mixed with the propellant fluid.
