Definitions

  • the invention relates to a media separation arrangement for use in a Exhaust gas recirculation device.
  • Exhaust gas recirculation devices are well known. It is in one Air intake duct an exhaust outlet opening that can be closed by a valve body an exhaust gas duct arranged such that generated by the internal combustion engine Exhaust gas in the air intake duct and thus to the intake tracts of the individual Cylinder of the internal combustion engine to reduce the amount of nitrogen oxide Internal combustion engine can be recycled.
  • a direct impact of the hot Exhaust gas from the exhaust duct to the fresh air in the air intake duct can in Connection with that deposited on the duct walls of the air intake duct Liquid such as B. (blowby, condensate, etc.) for the deposition of Pollution particles such as B. Soot on the duct walls of the air intake duct or lead on the valve closing body, which in turn the function of Exhaust gas recirculation device can impair.
  • the invention is therefore based on the object above to avoid the disadvantage mentioned.
  • the flow guide body is an essentially rectangular, bent sheet metal part with molded locking means, which as locking lugs and as Ring insert are formed. This ensures that the Media separation arrangement in the simplest way in the exhaust gas recirculation mixing housing can be used, the flow guide body ensuring that mixing of the Both media exhaust gas and fresh air only take place far behind the valve closing element.
  • FIG. 1 shows a media separation arrangement 1 according to the invention in one perspective view.
  • the media separation arrangement 1 consists essentially of a rectangular, bent sheet metal part 2 and locking lugs 3 and one Ring insert 4, which acts as a latching means in wall areas 5 of an air intake duct 6 (see Fig. 2) until the media separation assembly 1 rotates and is arranged securely in the air intake duct 6.
  • FIG. 2 shows an exhaust gas recirculation device 7 with the media separation arrangement 1 is inserted in the air intake duct by means of the locking means 3, 4 such that the Flow guide body 2 in the region of an outlet opening 8 of an exhaust gas duct is arranged.
