  • First stage pressure regulator for a two-stage underwater breathing apparatus
    Patent number: 7921866
    Abstract: A first stage pressure regulator for a two-stage underwater breathing apparatus, comprises a second movable wall (16, 18) for separating a balance chamber (10) from an ambient exposed chamber (17) . The second movable wall is formed by a disk-shaped piston (16) which is slideably and non sealingly guided along the peripheral walls that delimit the balance chamber (10), and by an elastically deformable diaphragm (18), which overlies the side of the piston (16) facing forward the ambient exposed chamber (17) . The elastically deformable diaphragm (18) forms with said piston (16) a diaphragm type pressure relief valve (20, 318).
