The first inlet conduit is separated from the first chamber by a valve connected to a diaphragm. The second inlet conduit comprises an adjustable restriction, through which a constant small quantity of gas being delivered to the first chamber. The pressure regulating system also comprises an outlet conduit being directly connected to the first chamber and to the inlet of the user and a second chamber being separated from the first chamber by said diaphragm. To said second chamber a third inlet conduit, provided with an adjustable restriction, is connected, through which a constant small quantity of gas is delivered to the second chamber.
