Abstract

Un dispositivo indicador para indicar cuándo se ha excedido una diferencia de presión preseleccionada, que comprende una caja con dos lumbreras separadas por un diafragma elástico con una abertura en él, y un miembro movible empujado a relación de obturación con dicha abertura para impedir fugas a su través, seleccionándose la configuración del miembro y de la abertura de manera que, en uso, la aplicación de una diferencia de presión previamente elegida entre dichas lumbreras haga que el miembro pase parcialmente a través de la abertura a una posición en la que es retenido por el diafragma, estando provisto dicho miembro de medios para indicar que ha sido ciertamente retenido.
