Abstract

ELEMENTO DE CONDUCCION (1) FLEXIBLE CON UN FUELLE (2) DE METAL Y CON UNA MANGUERA METALICA (5) ALOJADA COAXIALMENTE EN EL FUELLE. EL DIAMETRO EXTERIOR DE LA MANGUERA (5) ES MENOR QUE EL DIAMETRO INTERIOR DEL FUELLE (2). EL FUELLE (2) POSEE EXTREMOS CILINDRICOS, CUYO DIAMETRO INTERIOR ES MENOR QUE EL DIAMETRO INTERIOR DEL FUELLE (2). POR OTRO LADO, LA SECCION EXTERIOR DE LA MANGUERA (5) ES IUGUAL A LA SECCION INTERIOR DE LOS EXTREMOS (3) DEL FUELLE (2). LOS EXTREMOS (3) DEL FUELLE (2), LOS EXTREMOS DE LA MANGUERA (5) Y LAS PIEZAS DE APOYO (7), QUE SE COLOCAN DESDE EL EXTERIOR SOBRE LOS EXTREMOS (5) SE UNEN ENTRE SI POR MEDIO DE UN PRENSADO EN SENTIDO RADIAL.
