Abstract

APARATO PARA INTRODUCIR Y RETIRAR TUBOS DE FIJACION REUTILIZABLES EN UN CONJUNTO DE COMBUSTIBLE RECONSTITUIBLE. INCLUYE DOS PLACAS MOVILES (66, 82) DISPUESTAS FRENTE A FRENTE, SOPORTANDO UNA DE ELLAS (66) TUBOS FLEXIBLES (68) PARA SU INTRODUCCION EN TUBOS DE FIJACION (48) MIENTRAS QUE LA OTRA (82) SOPORTA BARRAS DE ACCIONAMIENTO (84) PARA ENSANCHAR LOS TUBOS DE FLEXION. UNOS PASADORES (122) GUIAN LAS PLACAS MOVILES (66, 82) ENTRE DOS POSICIONES LIMITE. LAS PLACAS ESTAN ORIENTADAS (96) HACIA LA PRIMERA POSICION LIMITE. EL APARATO INCLUYE ADEMAS UNOS VASTAGOS (150) PARA INTERCONECTAR LAS PLACAS MOVILES EN DICHA OTRA POSICION LIMITE, Y UNA PLACA DE MONTAJE (92) QUE SOPORTA LOS PASADORES (122), LOS VASTAGOS DE CONEXION (150), Y UN VASTAGO (100) PARA ELEVAR Y BAJAR LAS PLACAS MOVILES, INCLUYENDO LA PLACA DE MONTAJE MEDIOS (112, 114, 116, 120) PARA EL MONTAJE OPERACIONAL DEL APARATO EN UNA TOBERA SUPERIOR (20) DEL CONJUNTO DE COMBUSTIBLE.
