Abstract (en)
The pressure-relief valve assembly (9), coupled to the diaphragm (5) lever (27) by a rod assembly (15, 22) traversing the internal cavity (8) of the casing (1), comprises means (16, 21) for heat exchange with the surrounding environment, a rod support (24), at the end of the rod assembly (15, 22) opposite the valve assembly (9), also being advantageously combined with heat-exchange means (32, 33) so as to prevent icing, under the effect of the pressure-relief of the breathing gas in the casing, of the mechanical equipment for controlling the valve assembly when used in a cold environment. <IMAGE>
