Abstract (en)
[origin: EP1031665A2] A connection socket (45) located in the pipe (44) has a suction part (1), which decreases nozzle-like in flow direction, and then widens to pipe cross section size. The part has a suction aperture (5) in/behind the smallest cross section, which is connected via a pipe (12,18,20) to a container (22) for the additive (23). A throttle valve (19) between container and suction part acts as flow regulator and/or closure device. A back pressure valve (6) is also located between container and part, and there is mixing device downstream behind the suction part.
