ABSTRACT:
A heating and/or air conditioning apparatus for an automotive vehicle includes an inlet duct for supplying ambient air from outside the vehicle and dividing into a first branch and a second branch. A heat exchanger is mounted in the second branch, and the first and second branches communicate with each other through a junction, at which a control means is situated. The latter enables the temperature of the air leaving the outlets from the apparatus to be varied. A flap valve with two flaps, pivotting about an axis, is arranged in the said junction close to that edge of the junction which is nearest to the heat exchanger.
