An apparatus for pneumatic control of supercharging pressure in a turbocompressed engine, characterized by the fact that the spring of a pneumatic actuator opens a dump valve, and that a collection pipe receives the pressure in the intake pipe above the butterfly valve and below the compressor and transmits the pressure to two parallel tubes, one leading to the closing chamber of the actuator, and the other leading through a throttling constriction to the opening chamber of this actuator, which chamber communicates through a tube and through a pressure valve with the atmosphere, while a third tube supplies the control chamber of the pressure valve.
