Abstract
The expansion valve unit, coupled to a lever of a diaphragm by means of a rod unit extending through the internal cavity of the housing, includes heat exchange with the surrounding medium, a rod support at the end of the rod unit opposite the valve unit, being also advantageously associated with a heat exchange unit so as to prevent icing, under the effect of expansion of the breathing gas into the housing, of the mechanical control train of the valve unit, in case of use in a cold surrounding medium.
