Abstract

La presente invención se refiere a un cuerpo o etapa de turbina que lleva una rejilla de álabes fijos, solidarios con el estator de la turbina, que soporta un diafragma seguido de una rejilla de álabes móviles montada sobre un disco solidario con el rotor de la turbina, dicha rejilla de álabes móviles lleva en su cúspide una guarnición de hermeticidad constituída de varias cámaras, el disco lleva orificios de aspiración que desembocan en el espacio entre el diafragma y el disco y colocados en la vecindad de la parte periférica del disco, el cuerpo o etapa de turbina está caracterizada en que dichos orificios de aspiración estan conectados por canalizaciones que atraviesan al menos ciertos álabes móviles hasta los orificios de salida que desembocan en la cúspide de estos álabes, debajo de la guarnición de hermeticidad o en una cámara de la misma.
