Abstract

La presente invención se refiere a una turbina de geometría variable que comprende una rueda de turbina montada en una cámara de turbina, un pasaje anular de entrada dispuesto alrededor de la cámara de turbina, una cámara de entrada dispuesta alrededor del pasaje de entrada, y un pasaje de salida que se extiende desde la cámara de turbina, los pasajes y las cámaras comunicando de manera que el gas a presión admitido a la cámara de entrada fluya a través del pasaje de entrada al pasaje de salida, a través de la cámara de turbina, en donde una pared del pasaje de entrada está definida por un miembro anular de pared movible, la posición del cual con respecto a una pared confrontante del pasaje de entrada, es ajustable para controlar la anchura del pasaje de entrada, y paletas de boquilla se extienden a través de ranuras en el miembro anular de pared, a través del pasaje de entrada, caracterizada porque las paletas de boquilla se extienden desde un soporte de boquilla movible situado sobre el lado del miembro anular de pared remoto del pasaje de entrada, el soporte de boquilla estando dispuesto de manera que los extremos libres de las paletas se extienden a tope con la pared confrontante cuando el miembro anular de pared está situado a una distancia de la pared confrontante menor que una distancia predeterminada, y de manera que el soporte de boquilla se mueva con el miembro anular cuando el miembro anular de pared está situado a una distancia de la pared confrontante, mayor que dicha distancia predeterminada, con lo cual los extremos libres de las paletas de boquilla se mueven en alejamiento con respecto a dicha pared confrontante a medida que el miembro anular de pared se mueve en alejamiento con respecto a dicha pared confrontante, más allá de dicha posición predeterminada.
