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.

Claims (1)

  1. Vanne de commande de retour de gaz d'échappement (1) pour moteur à combustion interne, comportant un conduit de raccordement d'air (3) pour le circuit de dosage d'air et un conduit de raccordement de gaz d'échappement (4) pour le circuit de gaz d'échappement, et où
    un actionneur à électro-aimant (5) ouvre la vanne de commande de retour de gaz d'échappement (1) contre l'action d'un ressort de fermeture (6) pour dégager une surface de fermeture (11) de la vanne qui est fermée par un élément obturateur fixé à une tige (7), et
    la tige (7), qui traverse le conduit de raccordement d'air (3), présente une partie (9) qui dépasse d'un guidage de tige (8) et d'autre part entre dans une chambre (13) communiquant avec l'atmosphère dans laquelle le guidage de tige (8) entre également à son autre extrémité (12),
    caractérisée par le fait que
    la partie (9) qui dépasse du guidage de tige (8) présente une section (10) agrandie par rapport à la tige (7) qui correspond à peu près à la surface de fermeture (11) de la vanne, de sorte qu'une force agissant sur l'élément obturateur de la vanne est compensée par une force antagoniste agissant sur la partie (9) de la tige (7) qui dépasse du guidage de tige (8) et qu'ainsi, une pression dans le circuit d'aspiration d'air du moteur à combustion interne qui varie beaucoup en cas de fonctionnement avec turbocompresseur reste sans effets sur la caractéristique de fermeture de la vanne de commande de retour de gaz d'échappement.
