摘要

The device (110) has an insertion part (112) brought into a flowing medium i.e. inlet airflow, and provided with a longitudinal extending axle (114). The insertion part includes an inlet and main and bypass outlet openings. Main and bypass channels connect the inlet and the outlet openings. The insertion part includes a side wall in the region of the inlet, where the side wall has a swelling in the region of the inlet on its exterior. The swelling is round in shape, and a front edge of the side wall turned towards the inlet is rounded.
