    摘要： An apparatus for posttreatment of exhaust gases of an internal combustion engine, using a reducing agent to be introduced into the exhaust gases, in particular a urea or a urea-and-water solution, having an improved mixing chamber into which stored reducing agent, via a reducing agent line, and compressed air via a compressed air line can be introduced to create a reducing agent-air mixture, and means for preventing a reverse flow of reducing agent or reducing agent-air mixture from the mixing chamber into the compressed air line are provided which have a spring-loaded sealing hose. This arrangement assures secure sealing off of an attachable compressed air system from the corrosive reducing agent.

    摘要： The apparatus for generating a mixture of reducing agent and air has a pumping agent feed pump having a pump housing and a mixing chamber into which reducing agent and air pumped by the feed pump can be introduced; the mixing chamber is embodied in a mixing chamber body which communicates directly with the pump housing of the feed pump and forms a cap of the pump housing. The feed pump has a drive shaft which protrudes into the pump housing, and the mixing chamber body is disposed at least approximately radially to the drive shaft The apparatus has a compact structural size and only a slight reducing agent-filled idle volume.

    摘要： An apparatus for metering a urea or a urea-water solution for delivery to a catalytic converter assembly for removing nitrogen oxides from the exhaust gases of a Diesel engine, includes a housing block supporting function components communicating via a line, formed by recesses in the housing block, for transporting the reducing agent, and the walls of the line are formed by the housing block. This apparatus assures a simple line layout for reducing agent with a minimum number of sealing points that is accordingly appropriate for large-scale mass production.
