摘要

The device (1) has a supply line (12) provided for one of fluids (3) i.e. reducing agent (5). The supply line is encompassed by an enclosing tube (15) for formation of a venturi-nozzle. The supply line ends in the enclosing tube at a distance to an enclosing tube end (16). The enclosing tube has a diameter reduced outlet (17) at an end side. The enclosing tube has a wall-sided inlet opening (22) for other fluid (2) i.e. exhaust gas (4). The inlet opening has guiding elements i.e. adjustable flaps, for the latter fluid. The supply line is designed as a capillary or a double walled tube.
