The invention relates to a controllable two-way valve (), in which a valve rod () is connected in a permanent manner to at least two valve members (), the valve rod () being actuated by means of an actuator (). The housing () comprises an inlet () or outlet and two corresponding outlets (), () or inlets. According to the invention, the two valve members () correspond with at least two valve seats () and the two or more valve members () have three control surfaces (). The invention thus provides a dirt-resistant valve, which is easy to operate, has fixed valve members and does not require additional equipment. Said valve permits both the inlet to be completely blocked and the two outlets to be controlled independently of one another.

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.

Exhaust gas recirculation system for a combustion engine

Exhaust gas feeding device for a internal combustion machine for introducing exhaust gas into a suction channel section of an intake manifold through at least one opening, having an exhaust gas feed section, an exhaust gas feedback valve and an exhaust gas introduction plate that forms a annular channel in the wall region of the suction channel section, wherein the exhaust gas introduction plate is designed as a stamped part with formable webs in such a manner that the webs define a ring channel annular channel with openings in the built-in state of the exhaust gas introduction plate.
