Abstract
Una unidad (32) de caja en T que incluye un alojamiento (34) de la caja en T, un manguito (50) termico acoplado con el alojamiento de caja en T, una cuna (54) cruciforme, una estrella (52) que acopla en forma enroscada el manguito termico, y un perno (56) de extraccion que acopla la cuna cruciforme y la estrella. Por lo menos una arandela (74) elastica esta ubicada entre el extremo (72) del manguito termico y el extremo (64) de la pieza de transicion de la boquilla de rociado del nucleo. El alojamiento de caja en T incluye una abertura (80) de cubierta que tiene una pluralidad de orejas (84) de cierre en corte extendidas dentro de la abertura de la cubierta. Una placa (82) de cubierta incluye una porcion (88) de cabeza y una porcion (90) de insercion. Una pluralidad de orejas (86) de cierre en corte se extiende desde la periferia de la porcion de insercion. Una pluralidad de dientes de trinquete (92) se extiende alrededor de la periferia de la porcion de cabeza. Un resorte (96) de cierre incluye una porcion (102) de acoplamiento que tiene una pluralidad de dientes de trinquete (104) con las dimensiones adecuadas para embonarse con los dientes de trinquete de la placa de cubierta.
