<p>Pressure regulator for the first stage of two-stage aqualungs, comprising a high-pressure gas inlet (5), a high-pressure chamber (201) communicating with this inlet an intermediate-pressure chamber (203) and a reducing valve (301) interposed between said high- pressure chamber and said intermediate-pressure chamber. Said intermediate-pressure chamber and optionally also said high-pressure chamber are provided with a plurality of outlets. The high- pressure chamber, the reducing valve and the intermediate-pressure chamber are assembled in a cylindrical body (1). The intermediate-pressure outlets (103) and also, if present, the high-pressure outlets (102), are formed in annular bodies (2,3) mounted leaktightly against the escape of compressed fluid in such a way that they can be turned freely about the axis of said cylindrical body and such that they communicate via suitable ports and/or manifolds with said chambers (201,203) of the pressure regulator <IMAGE></p> |
