<p>An actuator assembly for a multi-blade damper includes a base plate havi ng slots extending longitudinally thereof and slidably receiving drive portions of the louver shafts. A series of drive slots extending generally perpendicular to the clearance slots is formed at each side of the clearance slots. A series of link assemblies are keyed to the shafts, the link assemblies including actuator pins extending into selected ones of the drive slots. A clamp connection interpos ed between the link and drive portion of the louvers permits relative adjustmen t of the link relative to the louver. Movement of the base plate parallel to the plan e defined by the axes of the louvers results in tilting of the louvers in a selected direction, dependent upon which of the series of drive slots is occupied by a pin of a respective link.</p> |
