Abstract
An actuator assembly for a multi-blade damper includes a base plate having 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 interposed between the link and drive portion of the louvers permits relative adjustment of the link relative to the louver. Movement of the base plate parallel to the plane 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.
