Claim 1:
2. The ventilation device according to claim 1, wherein:
the mixing duct is bounded in the longitudinal direction by a separating wall, in which the second guide is formed;
on the side of the separating wall facing away from the mixing duct, an additional mixing duct is formed, which is bounded in the longitudinal direction by the separating wall;
the first and second supply ducts lead into the additional mixing duct in the mixing section;
in the mixing section, on the side of the separating wall facing away from the mixing duct, a third guide running in the transverse direction and a fourth guide located opposite the third guide in the longitudinal direction and running in the transverse direction are provided;
the third guide and the fourth guide each has two guide walls running in the transverse direction and located opposite one another in the height direction;
at least one of the guide walls of the third guide slopes away with respect to the longitudinal direction from the other guide wall at a slope angle, and at least one of the guide walls of the fourth guide slopes away with respect to the longitudinal direction from the other guide wall at a slope angle;
the ventilation device includes an additional valve comprising a blade body, the blade body has a first guide section adjustably guided in the transverse direction in the fourth guide and has a second guide section adjustably guided in the transverse direction in the third guide;
the actuator, during the operation adjusts the additional valve in the transverse direction between a first position, in which the additional valve fluidically separates the second supply duct from the additional mixing duct and opens a fluidic connection between the first supply duct and the additional mixing duct, and a second position, in which the additional valve fluidically separates the first supply duct from the additional mixing duct and opens a fluidic connection between the second supply duct and the additional mixing duct; and
the first guide section of the additional valve has a first thickness running in the height direction, which is smaller than a second thickness of the second guide section of the additional valve running in the height direction, in such a manner that both guide sections of the additional valve are each in contact with both guide walls of the associated guide.
