摘要

The pipe (14) has an exit region formed by a wall of the pipe. The wall includes an indentation in the exit region, through which an effluent stream flows into two areas, where the stream is divisible into separated partial streams. A bend portion returns the effluent stream back between an entry region and the exit region, where the pipe is opened in a region of the indentation in a radial direction, and the depth of the indentation is smaller than the width of the partial stream in the exit region towards the depth of indentation. The indentation is arranged in the center of in the pipe.
