Operating element

The element (1) has a circular operating knob (3) provided for controlling direction of airflow via a clutch transmission i.e. linkage. The circular operating knob is rotated in horizontal and vertical directions. A circular control wheel (2) and a pivoted lever are arranged around the operating knob. An adjusting element is tilted or rotated about an axis running radially in a center longitudinal axis of the operating knob in a center position for adjusting size of the airflow. The control wheel controls the airflow via connecting mechanical devices i.e. gear wheel devices.
