A hand-operated device for underwater immersion equipment, which essentially comprises two reduction valves, the first one in communication with a high pressure breathing gas tank, from which, through said valve, it passes to a chamber of reduced and constant pressure that in turn, it is communicated through the second valve with a chamber whose pressure is maintained equal to the pressure of the water in which the spindle is located, thanks to the existence in said chamber of an elastic membrane in contact, by one of its faces, with the ambient water and which moves with pulsating movement to each inspiration of the swimmer, causing the opening of the second valve.
