The inlet has two swingable closing parts (SE) moved around pivot axles. Each of the closing parts comprises a pointing cylindrical outer surface facing in direction of airflow to be steered and to be cylindrical to a pivotal axis among two pivotal axes assigned to the closing part. The closing parts are formed as a portion of a cylinder jacket. The two closing parts are arranged parallel to each other in a frame (R). The pivot axles are extended parallel to one another. The closing part is formed to the airflow of opposite side which is steered on a concave arranged body. |
