Air outlet for use in e.g. road vehicle, has hollow body with air guidance unit, which is arranged in hollow body, so that rushing air generates torque, which displaces body in rotation

摘要

The outlet has an air guiding channel (1) with a rotation-symmetric hollow body (2) rotatably supported around an axis (4), which lies in the air flow direction. The body has an air guidance unit (3), which is arranged in the hollow body, so that the rushing air generates a torque, which displaces the body in rotation. The channel has a blocking unit, which enables the rotation of the hollow body in one operation position and restricts the rotation of the body in the other operation position.
