ABSTRACT:
An exhaust gas recirculation system for a combustion engine is proposed that includes all important functions within a housing. For this purpose an exhaust gas recirculation valve, an exhaust gas cooling device with a heat exchanger unit, as well as a bypass channel with a bypass flap likewise embodied in the housing, form a unit. In addition, the exhaust gas recirculation valve in the area of its valve seat is cooled by the coolant of the exhaust gas cooling device. Thus a solution is proposed that, in comparison with known exhaust gas recirculation systems, greatly reduces construction space and weight, at the same time features low-cost assembly, and is also to be implemented very cost-effectively by the possibility of producing all housing parts in the die-casting method.
