Abstract

A device (4) for introducing a liquid reducing agent (5) into an exhaust gas (6) of a combustion system (2) has a reservoir (20), a discharge element (23) for discharging the liquid reducing agent (5) into the exhaust gas (6), a feed line (22), interposed between the reservoir (20) and the discharge element (23), a delivery element (26) arranged in the feed line (22) for delivering the liquid reducing agent (5) in a direction of delivery (29) from the reservoir (20) to the discharge element (23). The feed line (22) is associated with a controllable venting element (34) upstream of the delivery element (26), the discharge element (23) is connected to the reservoir (20) via a return line (32) and a controllable shut-off element (36) is arranged in the return line (32).
