摘要：The present invention relates to a metering module (15) for a liquid reducing agent, in particular a urea-water solution, for mixing the reducing agent with a gas, in particular air, for further introduction into an exhaust pipe (5) of an internal combustion engine (1). The metering module (15) comprises a metering valve (31) having a conduit (33), a compressed air duct (49) and a mixing chamber (35). An outlet opening of the conduit (33) for the reducing agent is arranged in the mixing chamber (35) at a distance from the mid-axis of the metering module (36).
