Abstract (en)
The valve is operated by an electromagnet (5) which opens it against the opposition of a closure spring (6) to connect the exhaust pipe to the air intake system. The valve rod (7) protrudes through the air duct (3) from a section (9) within a guide (8) whose cross-sectional area (10) corresponds to that of the seating (11). The other end of the guide opens into a chamber (13) vented to atmosphere. Forces on the valve during a surge in the intake system are compensated by the counter-pressure on the protruding section of the rod.
Abstract (de)
Das neue Abgasrückführsteuerventil zeichnet sich dadurch aus, daß eine den Luftanschlußkanal (3) durchragende Ventilstange (7) einen aus einer Stangenführung (8) herausragenden Abschnitt (9) aufweist, dessen Querschnitt (10) in etwa der Ventilschließfläche (11) entspricht, wobei die Stangenführung (8) mit einem anderen Ende (12) in eine Kammer (13) hineinragt, die atmosphärisch belüftet ist. <IMAGE>
