In this supercharging device for internal combustion engines, comprising a turbine driven by the engine exhaust gases, an air compressor driven by the turbine and connected to the engine intake manifold, and a so-called exhaust-gas waste-gate responsive to a valve control valve responsive in turn to the compressor output pressure, this control valve being also responsive to a pilot valve responsive to the detection of the engine intake governing the valve control when opening the waste-gate at low engine speeds and part-load engine operating conditions, and when closing the waste-gate at higher engine speeds, the portion of the valve control which is responsive to the compressor output pressure being connected to a venting member actuated gradually from a position of maximum opening of the intake control butterfly valve obtained during the stroke controlling the maximum engine power output, whereby in the portion of this stroke which follows the position corresponding to the fully-open position of the butterfly valve the actual power output is subordinate to the closing of the waste-gate as a function of the degree of actuation of the venting member.
