Disclosed is a system for recirculating exhaust gas in an internal combustion engine having an exhaust gas recirculating conduit which is provided with a valve controlled by two solenoid windings. The system includes a control device including a PID regulator having limitations and cooperating with a three-point switching circuit which exhibits a hysteresis and includes a feedback. The energizing signals for the two solenoid windings are limited between a minimum and a maximum value, whereby the minimum value is defined by the operational sensitivity of the exhaust gas recirculating valve.
