Abstract

Perfeccionamientos en los dispositivos de amortiguación para una corriente de líquido, con una caja con un nivel de líquido, sobre el que se encuentra un colchón neumático de aire, estando conectada la caja a una tubería de entrada que conduce a ella, y conduciendo desde el recinto del líquido de la caja hacia fuera una tubería de salida, que se caracterizan por el hacho de que la caja está conectada a la tubería de entrada a través de una pieza de paso que se ensancha en forma de difusor, y por el hecho de que en el extremo de la pieza de paso se encuentra una placa perforada, que se extiende sobre toda su sección, con canales verticales, paralelos, teniendo los canales de la placa perforada, tramos que se ensanchan escalonadamente en la dirección corriente.
