Exhaust gas recirculation system

The exhaust gas return system has an exhaust gas return valve (9) with two valve members (17, 19). One of these controls the outlet (10) to the induction manifold, and the other the connection between the two exhaust paths (3, 4). The same valve has inlets (7, 8) to the exhaust paths and an outlet (10) to the induction manifold (11).
