Abstract

EL UTIL INYECTOR PARA LA CREACION DE UNA ACANALADURA (6) INTERIOR EN UN TUBO-ACCESORIO (5) COMPRENDE UN MACHO (3) QUE DISPONE DE UN REBORDE ANULAR, MOVIBLE HACIA FUERA Y HACIA DENTRO, QUE CONFORMA ESTA ACANALADURA. EL REBORDE ANULAR CONSISTE EN UN PRIMER Y UN SEGUNDO GRUPO DE SEGMENTOS (7, 8) . LOS SEGMENTOS (7'', 8'') ALTERNAN ENTRE SI Y SON PORTADOS CADA UNO POR UNA PALANCA ACODADA (13, 26). EL BRAZO RADIAL (14, 29) DE CADA UNA DE ESTAS ENCAJA EN LA RANURA LONGITUDINAL (11, 12) DE UN MANGUITO DE ANILLO (9) ASOCIADA A CADA UNO DE LOS SEGMENTOS (7'', 8''). EL MANGUITO (9) PUEDE DESPLAZARSE HIDRAULICAMENTE A LO LARGO DE UN SOPORTE CILINDRICO DE MACHOS (4). AL SER EMPUJADOS HACIA ATRAS LOS MANGUITOS (9), LOS SEGMENTOS (7'', 8'') DE AMBOS GRUPOS (7, 8) SE DESBLOQUEAN PRIMERO. UNA SUPERFICIE FINAL (22) DE UNA RANURA (11) TOPA A CONTINUACION CONTRA EL BRAZO RADIAL (14) DE LA PALANCA DEL PRIMER GRUPO DE SEGMENTOS (7), GIRANDO A ESTE HACIA DENTRO. AL SER EMPUJADO MAS ATRAS, EL MANGUITO (9) ARRASTRA TODALA PALANCA ACODADA (13), QUE SE ENCUENTRA GIRATORIAMENTE SOBRE UN ANILLO (20) AXIALMENTE DESPLAZABLE Y RETIRA LOS PRIMEROS ELEMENTOS (7'') AXIALMENTE HACIA ATRAS. LA SUPERFICIE FINAL (30) DE LA OTRA RANURA (12) TOPA, POCO ANTES DEL FINAL DEL CARRIL DE DESLIZAMIENTO DEL MANGUITO (9), CONTRA EL BRAZO RADIAL (29) DE LA PALANCA, GIRANDO EL SEGMENTO (8'') DEL SEGUNDO GRUPO DE SEGMENTOS (8) HACIA EL INTERIOR DEL MACHO.
