Abstract

The apparatus for controlling a damper in an air conditioning system for a vehicle. The damper is used for selectively opening air outlets, and is constructed as a film damper having one end wound on a drive shaft rotatably supported in a casing. The drive shaft is formed as a hollow shaft having an axial bore therein, in which an electric motor with a reduction gear is arranged. The outer body of the motor is fixedly inserted to the shaft, and has an output shaft fixedly connected to the casing, so that a rotation of the motor causes a relative rotation between the motor body connected to the hollow shaft and the outlet shaft connected to the casing. As a result of the rotation of the motor body, the drive shaft is rotated, resulting in a desired movement of the film damper.
