A first stage regulator for two-stage delivering assemblies includes a first chamber connected through an inlet to a high pressure gas source; a second chamber for the breathable gas at an intermediate pressure, which is connected to a user; a pressure reducing valve connecting the first and the second chambers and having a valve seat and a cut-off that cooperates with the valve seat and is displaceable from a closed position to an open position thereof and vice versa. The cut-off is dynamically connected to a sensor exposed to the external pressure and includes a transmitting element of the mechanical stress exerted on the sensor by the external pressure. The sensor includes a movable wall that is sealingly slidable in a housing chamber and constitutes the interface wall towards the outside, and the transmitting mechanism connects the movable wall with the cut-off.
