Abstract

Perfeccionamientos en la construcción de dispositivos difusores de membranas, que comprenden una pila de pares de paredes membranosas y de soportes de éstas en relación alternante e interpuesta que va dispuesta en una envoltura y que presenta unos extremos opuestos, definiendo las paredes internas de la envoltura un ángulo de extracción, caracterizados en que se disponen unas cuñas rígidas espaciadas en las esquinas exteriores de la citada pila, entre ésta y las paredes internas de la envoltura, estando dichas cuñas rígidas ahusadas y dotadas de unas proporciones que permiten la compresión de las porciones terminales de la referida pila entre dichas paredes internas de la envoltura y tales cuñas, en un grado generalmente igual a todo lo largo de estas cuñas rígidas.
