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.
  • exhaust gas recirculation valve are between the valve and the flange that with the intake port of the internal combustion engine is connected, cooling channels provided by the Coolant of the internal combustion engine are flowed through. By means of these cooling channels Although the exhaust gas recirculated from the valve to the intake duct is cooled, the valve is even burdened with the high exhaust gas temperature.
  • the invention has for its object to provide an exhaust gas recirculation valve To create cooling water of the internal combustion engine coolable flange module, in which the Cooling in the flange module provides thermal relief for the valve elements of the Exhaust gas recirculation valve causes.
  • a cooling channel encloses the flange module to the exhaust gas recirculation valve leading exhaust duct.
  • a preferred embodiment provides that the leading to the exhaust gas recirculation valve Exhaust duct runs in a partial area coaxial to the central axis of the exhaust gas recirculation valve and that this portion of the exhaust duct is surrounded by an annular cooling duct. In this way, an optimal temperature reduction of the exhaust gas recirculation valve exhaust gas can be achieved.
  • the flange module of the exhaust gas recirculation valve is for direct connection to the cylinder head of the internal combustion engine with a first Connection flange with inlet and outlet openings for the coolant of the cooling circuit and provided with an exhaust gas inlet opening, and has a second connection flange with a Exhaust outlet.
  • the two connecting flanges are preferably opposite one another formed on the flange module and run at different inclined acute angles to the central axis of the exhaust gas recirculation valve.
  • the exhaust gas recirculation valve can be directly on Cylinder head with the cooling circuit of the internal combustion engine and with an exhaust duct of the Connect the internal combustion engine.
  • the connection is made via the second connection flange to the intake duct of the internal combustion engine.
  • Figure 1 shows the exhaust gas recirculation valve 1 with flange module 2 according to 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 easily be 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.
