Abstract

Se proporciona un dispositivo de sellado que tiene mayores rendimientos de sellado mediante la eliminación de la presencia de fuga de gotas. Se proporciona un dispositivo de sellado 1 que tiene, en una superficie inclinada A del lado atmosférico 24 de un labio de sellado, un tornillo de dirección directa 26 que se extiende en una dirección que forma un ángulo de ataque con respecto a una dirección Z de rotación directa de un eje de rotación 2 y ejerce acción de bombeo con respecto al fluido objetivo de sellado durante la rotación directa del eje de rotación 2 y un tornillo de dirección inversa 27 que se extiende en una dirección que forma un ángulo de ataque con respecto a una dirección de rotación inversa del eje de rotación 2 y ejerce acción de bombeo con respecto al fluido objetivo de sellado durante la rotación inversa del eje de rotación 2, en donde se proporciona un tornillo de prevención de goteo 29 para el fluido objetivo de sellado en el lado del tornillo de dirección inversa 27 de la superficie inclinada 24 de modo que se ubique en una región para formar el ángulo de ataque.
