Abstract
La presente invención se refiere a un cuerpo o etapa de turbina de acción que lleva una rejilla de álabes fijos, solidarios con el estator de la turbina, que soporta un diafragman, seguido de una rejilla de álabes móviles montados sobre un disco solidario del rotor de la turbina, el cuerpo o zona de la turbina está caracterizada en que dicho disco está provisto de canalizaciones transversales, paralelas al eje del rotor, y en que las entradas de dichas canalizaciones que desembocan en el espacio entre el diafragma y el disco, están provistas de achicadores abiertos lateralmente, en el sentido de la rotación para enviar el fluido hacia el interior de las canalizaciones.
