<p>The regulator (1) has a body (2) comprising a pressurized gas intake chamber (5) connected to a respirable gas reserve and an expansion chamber (6) connected to a respiratory mouthpiece. The chambers are separated by a valve (8) moving between opening and closing positions under the action of a calibration spring (13). A lever (10) separating the expansion chamber from ambient water is supported on a deformable membrane (60). The spring has a support end rested against a bearing surface of the body to authorize circulation of ambient water around totality or majority of turns of the spring.</p> |
