Between the exhaust gas inlet duct and the exhaust gas outlet ducts, a distributor element driven by the rotational speed of the camshaft is arranged in the housing, which has a passage opening through which a fluidic connection of the exhaust gas inlet duct with one of the exhaust gas outlet ducts is produced during rotation of the distributor element. A phase shift for the upstream or rearward storage of the exhaust gas or for adaptation to changed opening times of the intake valves is not provided.
  • the distributor element is connected via a coupling with the camshaft and rotates at the speed of the camshaft. This can be ensured for example via a positive coupling or via corresponding gear or belt drives. In this way, the drive of the distributor element acts at exactly the same speed as the camshaft, so that the cycle accuracy is ensured in a simple manner.
  • the distributor element has an inlet opening which has a fluidic connection to the exhaust gas inlet channel and an outlet opening which can be connected to one of the exhaust gas outlet channels.

  • a control can be performed, for example, as a hollow cylinder open on one side and thus radially surround the distributor element.
  • the passage openings may be of the extent in the circumferential direction about the size of the outlet opening of the distributor element, so that to a certain Time per revolution an exact overlap of both openings would be present. At this time, the maximum exhaust gas flow would be returned to the respective cylinder.
  • the exhaust gas quantity regulator is formed by the control, which is arranged axially displaceable in the housing, wherein the axial height of the passage opening corresponds to the height of the adjoining ends of the exhaust gas outlet. This means that would be reduced by an axial displacement of the control, the respective opening window compared to the exhaust gas outlet. As a result, an exhaust gas quantity control would be possible with simultaneous possible phase shift. This means that with few components, both the recirculated exhaust gas quantity and the time could be adapted exactly to the requirements of the internal combustion engine.
  • control element is designed as a rotatably arranged disc with a number of axial passage openings corresponding to the number of cylinders and is arranged between a distributor element rotating at the speed of the camshaft with an inlet and outlet opening and a part of the housing, in which a number of exhaust gas outlet ducts corresponding to the number of cylinders is formed, wherein the ends of the exhaust gas exhaust gas ducts facing the control element have a greater extent in the circumferential direction than the through openings of the control element.
