Abstract

Problema Para mejorar la resistencia al agua con lodo en un dispositivo de sellado con una estructura donde un borde de sellado colocado en uno o dos miembros que giren relativamente y una brida de sellado colocada en el otros de los dos miembros se encuentran en contacto deslizante. Medio de resolución Un dispositivo de sellado, que comprende un cuerpo principal de dispositivo de sellado 1 colocado en uno de dos miembros 101 que giran relativamente y una brida de sellado colocada en el otro de los dos miembros 102; donde, el cuerpo principal del dispositivo de sellado 1 se proporciona con una estructura con un borde de sellado 12 conectado de forma deslizante a una brida de sellado 22 y una parte tubular 18 posicionada más hacia el lateral externo que el borde de sellado 12; se proporciona un borde laberíntico 15 en el cuerpo principal del dispositivo de sellado 1 posicionado más hacia el lateral externo que el borde de sellado 12; y este borde laberíntico 15 se extiende hacia el lateral opuesto radialmente hasta el extremo de punta de la brida de sellado 22 que se encuentra orientada hacia la parte tubular 18 en una dirección radial, a medida que el extremo de punta se orienta lo más posible hacia la brida de sellado 22 en una dirección axial y se forma un espacio laberíntico 3 entre el borde laberíntico 15 y la brida de sellado 22, y la parte tubular 18. Dibujo seleccionado Fig. 1.
