Abstract
Apparatus to supply breathing gas to a diver. A pressure-reducing valve is opened and closed by a piston actuated by an extended rod whose end is coupled to an articulated control lever which is driven by a diaphragm. By increasing the distance from the articulated lever, through the rod to the pressure-reducing valve, the risk of icing caused by cooling energy generated at the pressure-reducing valve when the diver operates in very cold water is eliminated.
