Definitions
- the invention relates to an exhaust gas recirculation valve for an internal combustion engine according to the Preamble of the main claim.
- a similar control valve is e.g. B. Subject of DE-A-42 04 434. It has been shown that this control valve the pressure pulsations in the intake and exhaust system Internal combustion engines that are charged by means of turbochargers do not withstand and in opens in special cases if no exhaust gas recirculation is provided.
- the object of the invention is to find measures with which a generic control valve, for. B. for hard use Turbomotors is suitable.
- the drawing shows a partial section of an exhaust gas recirculation control valve according to the invention 1 for internal combustion engines, which with a control valve housing 2 or Connection channels 3, 4 to the air intake system and the exhaust system Internal combustion engine can be connected.
- the control valve housing 2 is with a Solenoid actuator 5 connected to the control valve against the force of a Closing spring 6 opens.
- the air connection duct 3 protruding valve rod 7 one from a Rod guide 8 has protruding section 9, the cross section 10 corresponds approximately to the valve closing surface 11, the rod guide 8 with another end 12 protrudes into a chamber 13 which is atmospheric is ventilated.

Description
Claims (1)
- Abgasrückführsteuerventil (1) für eine Brennkraftmaschine mit einem Luftanschlußkanal (3) für das Luftzumeßkanalsystem und mit einem Abgasanschlußkanal (4) für das Abgaskanalsystem, wobeiein Elektromagnetsteller (5) das Abgasrückführsteuerventil (1) entgegen der Kraft einer Schließfeder (6) öffnet, um eine Ventilschließfläche (11) freizugeben, die durch ein an einer Ventilstange (7) befestigtes Ventilschließglied verschlossen ist, unddie den Luftanschlußkanal (3) durchragende Ventilstange (7) einen aus einer Stangenführung (8) herausragenden Abschnitt (9) aufweist, welcher andererseits in eine atmosphärisch belüftete Kammer (13) hineinragt, in die ebenfalls die Stangenführung (8) mit ihrem anderen Ende (12) hineinragt,der aus der Stangenführung (8) herausragende Abschnitt (9) einen im Vergleich zur Ventilstange (7) vergrößerten Querschnitt (10) aufweist, der in etwa der Ventilschließfläche (11) entspricht, so daß eine auf das Ventilschließglied wirkende Kraft durch eine am aus der Stangenführung (8) herausragenden Abschnitt (9) der Ventilstange (7) wirkende Gegenkraft ausgeglichen wird, wodurch ein bei Turboladerbetrieb sehr stark schwankender Druck im Luftansaugsystem der Brennkraftmaschine ohne Auswirkungen auf die Schließcharakteristik des Abgasrückführsteuerventils bleibt.
