Definitions

  • the invention relates to an exhaust gas recirculation valve according to the preamble of claim 1.
  • An exhaust gas recirculation valve is known from EP 0 763 655 A2, which devices for Has cooling of the recirculated exhaust gas. This measure is intended to undesirable increase in temperature of the intake air can be largely avoided.
  • this known exhaust gas recirculation valve are between the valve and the flange, the is connected to the intake duct of the internal combustion engine, cooling ducts are provided, through which the coolant of the internal combustion engine flows. By means of this Cooling channels, the exhaust gas recirculated from the valve to the intake channel is cooled, however, the valve itself is exposed to the high exhaust gas temperature.
  • the invention has for its object to a generic exhaust gas recirculation valve create that with space-saving design effective cooling of the exhaust gas and ensures thermal protection of the valve.
  • a preferred embodiment provides that the leading to the exhaust gas recirculation valve Exhaust duct in a partial area coaxial to the central axis of the exhaust gas recirculation valve and this part of the exhaust duct runs from an annular cooling duct is surrounded. In this way, an optimal temperature reduction of the Exhaust gas recirculation valve reaching exhaust gas can be achieved.
  • the flue gas recirculation valve can be directly connected through the flange module designed in this way on the cylinder head with the cooling circuit of the internal combustion engine and with a Connect the exhaust gas duct of the internal combustion engine. Via the second connection flange the connection to the intake duct of the internal combustion engine is established.
  • Figure 1 shows the exhaust gas recirculation valve 1 with flange module 2 in accordance with the viewing direction R, which is shown in Figure 5 with an arrow. That as an electrical exhaust gas recirculation valve 1 trained valve is known per se. In connection with the flange module 2 this can be done Attach exhaust gas recirculation valve 1 directly to the cylinder head of an internal combustion engine.
  • This here visible first connection flange 3 has an inlet opening 4 and an outlet opening 5 for the Coolant.
  • it has an exhaust gas inlet opening 6 to which one can be easily attached angled arc extending recess 11 connects.
  • the connection to the cylinder for the entry of the exhaust gas is in area 7.
  • the opposite side of the flange module 2 can be seen in FIG. 2, specifically in Direction S of view of the second connecting flange 8 corresponding to that in FIG. 5 indicated arrow direction S.
  • the second connecting flange 8 has an exhaust gas outlet opening 9, via which a connection to the intake duct of the internal combustion engine is established.
  • the electrical connection 10 of the exhaust gas recirculation valve can also be seen in FIG.
