The device comprises a by-pass conduit (1) provided with a by-pass valve (3) on the exhaust gas turbine. The servomotor (4) of said turbine is supplied with air derived from the overcharging air. Up to a value which depends on a parameter of the overcharging air, the temperature and the ambiant pressure, the supply air of the servomotor (4) acts, through a control valve (8) and a pressure regulator (9), in the direction for closing the valve (3), and beyond said value, in the direction of its opening. |
