It comprises a cold air duct (10), a warm air duct (11) and a mixed air duct (12), the mixed air duct, also called primary air duct, is provided with a control flap (18), which in one final position closes off the cold air duct (10) and in the other final position closes off the warm air duct (11) and can pivot under the action of a wax-type thermostat (14) around which the cold intake air flows. The wax-type thermostat (14) is provided with a pull rod (16) connecting it to the control flap (18). A restoring spring (26) is located on the pull rod (16). The pull rod (16) is arranged on the side opposite to the wax-type thermostat (14) in a guide (17) that is fixedly coupled with a housing (20). In addition, an excess travel spring (24) is provided to compensate for the excess travel of the wax-type thermostat (14). The control flap (18) has longitudinal guiding means (21) and the excess travel spring (24) is arranged on a sliding element (23) that is arranged in said longitudinal guiding means (21).
