摘要

The device (10) has a storage container (14) provided with a receiving space (16) for receiving liquid reducing agent (12). A pump (20) conveys the reducing agent from the receiving space. A sucking element (24) is intended for post-treatment of exhaust gas of a vehicle. The reducing agent from the receiving space is conveyed to the duct element by the pump. A float element (28) is provided with an inlet opening and a filter element for filtering the reducing agent. A sensor detects amount and/or quality of the liquid reducing agent.
