ABSTRACT:
A device for simultaneously adjusting at least two pivoted elements, in particular valves used for air distribution in a vehicle heating or air-conditioning system, has an operating unit with a control disc which is connected to a rotary knob and a control groove which is closed upon itself and into which at least two levers engage which are pivotably accommodated by the operating unit and whose pivoting movements are transmitted to the pivoted elements. Simple tolerance compensation and installation without subsequent setting work is possible when each lever has a separate pivot bearing. The pivoting movements, occurring when the control groove is followed, of the bearing pin of each lever, with a universal-joint arrangement in between which leads away essentially in the axial direction of the bearing pins and permits length compensation, are transmitted from the operating unit to pivoted levers mounted on the heating box side.
