The invention relates to a valve for apportioning preheated and non-preheated air to an internal combustion engine. The valve has a pivotally mounted valve flap, which is rigidly joined to a balance flap which is so constructed and arranged in the valve body that the low pressure created by the airflow through the valve body gives rise to oppositely directed torques of substantially the same magnitude about the pivot shaft on the balance flap and the valve flap. |
