Abstract

La presente invención se refiere a turbina que tiene por lo menos un conjunto con un diafragma cortado en dos, según un plano diametral y que comprende una corona exterior y una corona interior, unidas por medios que sirven para guiar el fluido de la turbina, en que la cara corriente abajo de la corona exterior se aplica contra una corona del estator de la turbina y en que el diafragma está provisto de medios de hermeticidad que garantizan la hermeticidad entre la corona exterior y el estator; caracterizado en que los medios de hermeticidad se hallan dispuestos sobre el canto de la corona exterior, en que la cara corriente abajo de la corona exterior se halla provista de un apoyo distante del canto y se apoya sobre la corona del estator, y en que se proveen medios para asegurar la comunicación del espacio situado entre el apoyo y los medios de hermeticidad, con un espacio corriente abajo del diafragma, espacio que se halla a una presión inferior a la presión P1 establecida sobre la cara corriente arriba del diafragma.
