Abstract

DICHO SEPARADOR (42) PRESENTA UN RECINTO HUECO (46), ADAPTADO PARA SER MONTADO EN EL INYECTOR EXTREMO DE UN CONJUNTO DE COMBUSTIBLE, QUE SE COLOCA EN LA TRAYECTORIA DE CIRCULACION DEL REFRIGERANTE. EL RECINTO HUECO COMPRENDE UNA PARED SUPERIOR (48), UNA INFERIOR (50), Y UNA PARED LATERAL CONTINUA QUE UNE LAS ANTERIORES Y LAS SEPARA CON OBJETO DE DEFINIR UNA CAMARA DE RETENCION DE DESECHOS (54), ESTANDO AL MENOS LAS PAREDES SUPERIOR (48) E INFERIOR (50) FORMADAS POR UNA REJILLA DE MALLA DE ALAMBRE PERMEABLE AL REFRIGERANTE E IMPERMEABLE A LOS DESECHOS SUSPENDIDOS EN ESTE. LA PARED INFERIOR (50) ESTA PROVISTA DE AL MENOS UNA ABERTURA (58) Y MEDIOS DEFLECTORES (56), EMPAREJADOS AMBOS EN NUMERO Y ALINEACION CON LAS ABERTURAS DE CIRCULACION DEL REFRIGERANTE (30) CON OBJETO DE DIRIGIR LOS DESECHOS HACIA LA CAMARA DE RETENCION (54).
