Abstract

Perfeccionamientos en mecanismos automáticos para la descarga de agua en cisternas de inodoros, introduciendo en las mismas un factor de tiempo, caracterizados porque el mecanismo de descarga entra en funcionamiento una vez se ha bajado la tapa de la taza del inodoro, ya que la tapa en su movimiento desplaza un primer conjunto de palancas articuladas y girables una de las cuales, en su movimiento actúa, a través de un saliente sobre un trinquete que coopera en el desplazamiento de una varilla de descarga, verticalmente y hacia abajo, mientras que en las dos ultimas palancas del conjunto, se acoplan; un regulador, entre una de ellas y la varilla de descarga, y en la palanca extrema se acopla el vástago de un amortiguador y dos muelles, uno de recuperación del conjunto y el otro que actúa únicamente cuando se levanta la tapa, dependiendo el que se produzca una descarga total o parcial en que se ejerza o no una sobrecarga en dicha varilla, para lo cual al actuar el muelle de recuperación, el amortiguador tiene que encontrarse con un tiempo suficiente para que la palanca a la que va acoplada alcance una posición límite, para que el pistón del regulador actúe sobre un muelle interior que es el que, perfectamente dimensionado, hace la sobrecarga necesaria que producirá la descarga total, en caso contrario no actuara el muelle y se producirá la descarga parcial.
