The exhaust gas recirculation valve(11) for the air charging on the input side is connected to the air feed system of the secondary air valve(12). The air feed system for the supply of clean air from an air filter(14) leads to the secondary air valve. The exhaust gas recirculation valve is aerated by the clean air by means of a ventilation line(17) branching from an air feed line(15) in the air feed system. Between the air filter and secondary air valve a secondary air pump(16) interacts with the air feed line in such a way that the clean air is drawn from the filter and directed under pressure to the secondary air valve.
