DISPOSITIF DE SURETE EQUIPANT UNE CUVE DE CHAUFFAGE, NOTAMMENT A COMBUSTIBLE SOLIDE

摘要

The boiler is secured against an excessive temperature of the heated water by an apparatus which has a valve for opening a discharger, which can be opened by a displaceable element which cooperates with two bellows, one bellows being sufficient per se to open the valve, and the displaceable element being constructed such that a signalling element is actuated when one of the bellows undergoes an extension other than that of the other bellows. <IMAGE>
