Abstract

Perfeccionamientos en dispositivos de estanquidad para formar cierres herméticos contra el paso de líquidos entre dos superficies, caracterizados porque se dota a cada dispositivo de una montura para fibras flexibles que salen de la misma a modo de cepillo, cuya montura se fija de una manera prácticamente hermética al líquido a una de dichas superficies y se dispone para permitir que los extremos libres de dichas fibras, se extiendan de tal manera que permitan por lo menos una proporción de las mismas se pongan en contacto con la segunda de las superficies citadas.
