Abstract

Una máquina giratoria que incluye una carcasa 11 que tiene una forma hueca, un rotor 12 soportado de manera giratoria en la carcasa 11, un álabe del estator 13 fijo a una porción periférica interna de la carcasa 11, un álabe del rotor 14 fijo a una porción periférica externa del rotor 12, mientras que se desplaza desde el álabe del estator 13 en una dirección axial A del rotor 12, un dispositivo de sellado 15 colocado entre la porción periférica interna de la carcasa 11 y una punta del álabe del rotor 14, una cámara de generación del flujo arremolinado 31 proporcionada a lo largo de una dirección circunferencial C del rotor 12 en un lado corriente abajo del dispositivo de sellado 15 en la carcasa 11, en una dirección del flujo del vapor A1, y una pluralidad de elementos de orientación 32 proporcionados a distancias predeterminadas en la cámara de generación del flujo arremolinado 31 en la dirección circunferencial C del rotor 12. Los elementos de orientación 32 incluyen cada uno, una primera superficie de orientación 33 que se inclina en la dirección circunferencial C con respecto a la dirección axial A del rotor 12.
