    摘要: The invention relates to a device for the post-treatment of exhaust gases of an internal combustion engine, using a reductant that is to be introduced into the exhaust gases, in particular urea or a urea-water solution, comprising a mixing chamber, or relates to a mixing chamber, into which stored reductant can be introduced via a reductant conduit and compressed air can be introduced via a compressed air conduit to create a reductant-air mixture. The invention is provided with elements for preventing a reflux of reductant or the reductant-air mixture from the mixing chamber into the compressed air conduit. Said elements have a spring-loaded (112, 114) sealing hose (110). Said arrangement ensures that a connectable compressed air system can be reliably sealed against the corrosive reductant.
