  • Coolant connections 33, 34, 36, 37 are coordinated with each other here, that in the assembled state of a coolant connection (second coolant port 34) of the exhaust gas cooler 9 directly to the one coolant connection (third coolant connection 36) of the EGR valve 11 is connected so that on additional connectors can be dispensed with.
  • FIGS. 6 and 7 show others in this respect Embodiments, however, with regard to the others Features substantially identical to those described above Embodiments may be constructed.
  • each distribution channel 12, 12 ' is provided, each adjacent to all Frischgasaustritten 4 are arranged, where they each located in the immediate vicinity of the fresh gas outlets 4.
  • Each distribution channel 12, 12 ' communicates with the fresh gas distributor 2, wherein the distribution channels 12, 12 'here each with the discrete return openings 14 are equipped, and for each fresh gas outlet 4 each have a return opening 14.
  • a special feature is now seen in that the first output 21 to the one Distribution channel 12 is connected, while the exhaust outlet 27 connected to the other distribution channel 12 ' is.
  • FIG. 7 can also be a simultaneous and thereby separate supply of cooled and uncooled exhaust gases be realized in the fresh gas distributor 2, without that to two separate distribution channels 12 and 12 'as in the embodiment of FIG. 6 are required.
  • To this Purpose is the only distribution channel 12 by means of a Partition 38 in two separate distribution sub-channels Shared 12a and 12b.
  • Each of these distribution sub-channels 12a, 12b again extends adjacent to all fresh gas exits 4 and preferably communicates via discrete return port 14 with the fresh gas distributor 12.
  • Analogous to Variant according to FIG. 6 is the one distribution sub-channel 12a the first output 21 of the switching valve 10 is connected, while the other distributor part passage 12b to the exhaust outlet 27 of the exhaust gas cooler 9 is connected.
