Abstract
A motor-vehicle heating and/or air conditioning device has a cold-air duct, a hot-air duct housing a heating radiator, a mixing chamber communicating with respective air outlets of the ducts and a mixing means. The mixing means has at least one flap of drum type which, in the "hot" position, closes off the outlet of the cold-air duct, and, in the "cold" position, closes off the outlet of the hot-air duct. The shutter wall of the flap includes at least one recess such that, when the flap is shifted from the "hot" position to the "cold" position, a cold airflow can pass through the recess so as to encounter a hot airflow.
