#CMT# #/CMT# The wind impeller comprises rotation axis (10,12), which carries a rotating control curve (13). The control curve comprises curvature or a small radius on both sides of the angle range. A transition (30) provided with a transition curve (31) is formed between the curve range with a former curvature or small radius (27) and the latter curvature or large radius (28). A counter-stop piece (15) is adjusted by an increased torque at the control curve of the transition and the range of the larger radius against a restoring force and damper affects at the counter-stop piece. #CMT#USE : #/CMT# Wind impeller for advertising media in form of a sail carrying a message. #CMT#ADVANTAGE : #/CMT# The counter-stop piece is adjusted by an increased torque at the control curve of the transition and the range of the larger radius against a restoring force and damper affects at the counter-stop piece, and thus avoids damage of the angle range, and also enables resistance against swiveling of the sail. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a control disc of a wind impeller. 10,12 : Rotation axis 13 : Control curve 15 : Counter-stop piece 27 : Small radius 28 : Large radius 30 : Transition 31 : Transition curve. |
