Zusammenfassung:The temperature control for the vehicle fresh air heater has a control element which determines the relative setting of the mixer flap, using a thermal expansion element(5) which drives a reduction gearing(6) to operate on the setting control. The temperature control requires no complex electric servo control and operates directly on the heater linkage. The small movements of the expansion element are magnified by the reduction gearing, operating in reverse. The temperature is maintained at different vehicle speeds without any additional adjustment.
