A first stage pressure reducer for two-stage breathing groups, comprising a first chamber for a high-pressure breathable gas, a second chamber for the breathable gas at an intermediate pressure, a pressure-reducing valve which connects said first chamber and the said second chamber and which valve comprises a valve seat with a communication opening between said first and said second chamber and a shutter cooperating with said valve seat and movable from a closing position of said passage opening to a position opening of said passage opening and vice versa, said shutter being connected to a sensor member exposed to the pressure of the external environment comprising a transmission mechanism of the mechanical stress exerted on said sensor member by the pressure of the external environment to the shutter itself and in which said transmission mechanism is provided with a suspension/reactivation member of the kinematic transmission chain as a function of the mechanical stress exerted on it by the pressure of the external environment, the said suspension/reactivation member being provided with sensors of the said mechanical stress which suspend the kinematic transmission chain when the mechanical stress is below a predetermined threshold value and restore the kinematic transmission chain when said mechanical stress equals or exceeds said threshold value.
