Abstract
Regulator for underwater breathing apparatus of the type comprising a box-shaped body provided with a pressure-controlled membrane which divides the inside of the body into a first chamber communicating with the atmosphere and a second chamber communicating with a compressed-air inlet valve operated by a lever cooperating with said pressure-controlled membrane and also provided with an air discharge valve and a tube equipped with mouthpiece, characterized in that the box-shaped body of said regulator is made at least partially of thermally conductive polymers. Advantageously, said thermally conductive polymers used consist of engineering polymers having a matrix of polyamide, polycarbonate or PET (polyethylene terephthalate) or TPU (thermoplastic polyurethane) or the like containing metallic or graphite fibre or carbon fibre fillers dispersed within the polymer matrix.
