VENTILANORDNUNG FÜR EINE ABGASRÜCKFÜHRUNG BEI EINEM VERBRENNUNGSMOTOR

摘要

The valve device for exhaust gas feedback in an internal combustion engine comprises a controlled valve (1) whose valve plate (1a) cooperates with a valve seat (2) in a valve housing (7b). The exhaust gas inlet of the valve housing is connected via an exhaust gas feedback pipe (7) to the exhaust gas side of the internal combustion engine and the exhaust gas outlet is connected through a connecting pipe (16) to the induction side of the internal combustion engine. The valve housing is formed by an end section (7b) of the exhaust gas feedback pipe (7) itself and the valve seat (2) is formed by a constriction (8) formed in the end section. The pipe part (9) of the end section (7b) connected to the constriction (8) carries the regulating actuator housing (3). The pipe part (9) is provided at the side with an opening (14) forming the exhaust gas outlet and the connecting pipe (16) is brazed to the pipe part (9) in the region of this opening (14).
