Abstract
EL CONJUNTO COMBUSTIBLE COMPRENDE MEDIOS DE FIJACION RAPIDA DEL TUBO GUIA (4,'') EN UNA ABERTURA (11'') QUE ATRAVIESA LA PLACA ADAPTADORA (10'') DE UNA CONTERA DESMONTABLE (5'') DEL CONJUNTO. LOS MEDIOS DE FIJACION RAPIDA COMPRENDEN AL MENOS DOS TOPES DE APOYO (11''A) EN EL INTERIOR DE LA ABERTURA (11'') DE LA CONTERA, UN MANGUITO DE APOYO (16) SOLIDARIA AL EXTREMO DEL TUBO GUIA (4'') Y UN ANILLO DE BLOQUEO (18) QUE COMPRENDE TOPES DE APOYO (18D) SOBRE SUPERFICIES DE APOYO DE LOS TOPES (11''A) EN EL INTERIOR DE LA ABERTURA (11'') DE LA CONTERA Y DE LAS PARTES ELASTICAS DEFORMABLES (18B) SUSCEPTIBLES DE ALOJARSE EN CAVIDADES DE LA ABERTURA (11'') DE LA PLACA ADAPTADORA (10'') O DEL MANGUITO DE APOYO (16), PARA COLOCAR EL ANILLO (18) EN UNA POSICION DE BLOQUEO O DE DESBLOQUEO DEL TUBO GUIA (4''). EL MANGUITO (16) COMPRENDE UN REBORDE DE APOYO (16F) SOBRE UNA SUPERFICIE DE APOYO (10''A) DE LA PLACA ADAPTADORA (10'') EN LA PERIFERIA DE LA ABERTURA (11'').
