Definitions
- the invention relates to an exhaust gas recirculation arrangement according to the preamble of the main claim.
- Exhaust gas recirculation arrangements for improving the exhaust gas quality by reducing the No x emissions are known.
- the exhaust gas extraction from one exhaust gas line is too low be because the exhaust gas pulsates. Therefore, the exhaust gas must be removed from both lines for the purpose of recirculation to ensure that it is available in sufficient quantity.
- the invention is therefore based on the object, these opposite requirements by designing an exhaust gas recirculation valve.
- An internal combustion engine 1 has cylinder banks 2 arranged in a V-shape, from which each lead an exhaust line 3, 4 to a turbocharger 5, 6, respectively a branch line with the same number from the exhaust lines 3, 4 at the same time lead to the inlets 7, 8 of an exhaust gas recirculation valve 9.
- An outlet pipe 10 of the exhaust gas recirculation valve leads to an intake manifold 11 from which the Cylinder banks 2 are supplied and at the same time the pressure lines 12, 13th the exhaust gas turbocharger 5, 6 open.
- the exhaust gas recirculation valve 9 is constructed in such a way that it is of any design Servomotor 14 has. This can be pneumatic or electric motor his.
- the servomotor 14 actuates one as a function of operating parameters 15 Valve rod 16 on which a valve plate 17 is arranged, which is assigned to the outlet 10 is and there sealingly abuts a seat 18 in the closed position.
- a second valve member 19 is arranged, the a sealing area 20 one of the inlets 8 cooperates.
- the valve member 19 is gimbaled at the free end of the valve rod 16.

Description
Claims (3)
- Abgasrückführanordnung für einen Verbrennungsmotor (1) mit einem Saugrohr (11) und zwei getrennten Abgasleitungen (3, 4), denen Abgas mittels eines Abgasrückführventils (9) entnommen und dem Saugrohr (11) in Abhängigkeit von Betriebsparametern (15) zugeführt wird, dadurch gekennzeichnet, daß ein gemeinsames Abgasrückführventil (9) je Abgasleitung (3, 4) einen Einlaß (7,8) und zum Saugrohr (11) einen Auslaß (10) aufweist, wobei der Auslaß (10) von einem dichtend an seinem Sitz (18) anlegbaren Ventilteller (17) beherrscht wird, der fest mit einer von einem Stellmotor (14) antreibbaren Ventilstange (16) verbunden ist und an deren freien Ende ein zweites Ventilglied (19) angeordnet ist, das mit einem Dichtungsbereich (20) eines der Einlässe (8) zusammenwirkt.
- Abgasrückführventilanordnung nach Anspruch 1, dadurch gekennzeichnet, daß das zweite Ventilglied (19) als kardanisch an der Ventilstange (16) aufgehängter Ventilteller ausgebildet ist.
- Abgasrückführanordnung nach Anspruch 1, dadurch gekennzeichnet, daß das zweite Ventilglied kolbenförmig ausgebildet ist und unter Beibehaltung eines Ringspalts in eine zylindrische Bohrung am ventilseitigen Ende des Einlasses (8) einführbar ist.
