  • Axial-flow reversible turbine
    Patent number: 4293273
    Abstract: An axial-flow reversible turbine comprises a nozzle assembly and a wheel rotor mounted consecutively in the direction of the flow of the working medium and provided with two-section blades. One section of said blades forms the flow duct of the direct-rotating turbine and the other section, the flow duct of the counter-rotating turbine. The flow duct of the direct-rotating turbine incorporates a valve in the form of variable-incidence airfoil vanes intended to deny the access of the working medium into said duct. The inside diameter of the flow duct of the counter-rotating turbine is larger than the outside diameter of the flow duct of the direct-rotating turbine. The gas flow ducts of the direct- and counter-rotating turbines communicate with each other through a cylindrical bushing with ports.
    Type: Grant
