Abstract

La presente invención se refiere a una turbomáquina radial, que comprende una carcasa fija (6); al menos un disco de rotor (2, 2', 2") instalado en la carcasa (6) y que tiene alabes de rotor (3, 3', 3") montados en una cara frontal (4, 4', 4") de la misma; una pluralidad de elementos (25, 35) que se proyectan desde la carcasa (6) y que terminan en proximidad al disco de rotor (2, 2', 2"), en donde los elementos de proyección (25, 35) comprenden elementos de sello (34) que actúan contra el disco de rotor (2, 2', 2") que son operativamente activos en una cara posterior (9, 9', 9") del disco de rotor (2, 2', 2") o alabes de estator (13) radialmente interpuestos entre los alabes de rotor (3) del disco de rotor (2); at menos una placa de soporte (17, 37) que porta los elementos de proyección (25, 35) e instalada en la carcasa (6). La placa de soporte (17, 37) este radialmente extendida a través del disco de rotor (2, 2', 2") y comprende una pluralidad de primeras porciones circulares (29) concéntricas con un eje de rotación (X-X) del disco de rotor (2) y una pluralidad de segundas porciones circulares (30) radialmente interpuestas entre las primeras porciones circulares (29); al menos varias de las primeras porciones circulares (29) portan los elementos de proyección (25, 35) y las segundas porciones circulares (30) son más deformables, a lo largo de direcciones radiales, que las primeras porciones circulares (29) para permitir movimientos relativos entre las primeras porciones circulares (29) cuando la placa de soporte (17, 37) está sometida a la acción de gradientes térmicos.
