摘要

The device comprises a rotating axis (2) with one or more arms (3), where wings (4) are arranged at the arms and are supported in a swiveling manner. The wings are inclined in one position with a larger contact surface and inclined in another position with smaller contact surface. A flank area is inclined when it automatically moves into the former position with a stream (10) or in the latter position against the stream.
