Abstract
SE PRESENTA UN OBTURADOR MAGNETICO PARA EJES GIRATORIOS QUE TIENE UN PRIMER Y UN SEGUNDO MIEMBROS ANULARES (11, 12). CADA UNO DE DICHOS MIEMBROS ANULARES TIENEN UNA FUENTE DE FUERZA MAGNETICA (16) ESTANDO LAS LINEAS DE LA FUERZA MAGNETICA AXIALMENTE ALINEADAS CON EL EJE (10). UNA PIEZA ESTACIONARIA (13) SE SITUA EN DICHO ALOJAMIENTO (19) Y TIENE UNA CARA OBTURADORA (21) ADYACENTE A DICHOS MIEMBROS ANULARES. EL PRIMER Y EL SEGUNDO ANILLO ANULAR (11, 12) SE ENCUENTRAN GIRATORIAMENTE CONECTADOS ESTANDO EL SEGUNDO ANILLO (12) PEGADO AL EJE (10) Y A UNA CARA RELACIONADA CON DICHO SEGUNDO MIEMBRO PARA EFECTUAR UN CONTACTO DE OBTURACION CON LA CARA DE LA PIEZA (13). EL PRIMERO DE DICHOS ANILLOS (11, 12) SE ASEGURA AL EJE (10) PARA QUE EFECTUE UNA ROTACION ANULAR.
