摘要

The flow device for a scoop wheel trough is connected via a hose (3) to an ejector nozzle producing a water and air mixture. The end of the hose which protrudes into the trough (5) opens out into a bell-shaped outlet opening (1) connected by a sleeve (4) and distributing the water and air mixture. In the region of the lower encompassing edge of the outlet opening, congruent with the bell diameter, is located a L-shaped profiled strip (2) which is installed in such a way that the edge forming the apex point of the two legs (8) points downwards.
