Abstract
A turbine, including a rotor on a shaft, and having in combination stationary nozzles discharging steam at a first pressure or pressures thereby producing impulse forces on the rotor; internal passages in the rotor producing a pressure head increase in the discharged steam, while simultaneously accelerating the steam, the steam discharged to a second pressure lower than the first pressure, producing reaction forces on the rotor; seal means between the stationary nozzles and the rotor, maintaining the pressure difference between the first pressure and the second pressure while minimizing steam leakage past the internal passages, turbine operations producing shaft power.
