An air distribution valve (10) for use in a passageway of an environmental control system comprises a valve body (12) including an input (14), and multiple outputs (16, 18) defining a volume (24). The valve body is adapted for placement in the passageway for receiving the air in the input. A valve member (20) is used for selectively distibuting the air between the multiple outputs. Damping devices (34, 36) for damping the unstabilizing effect of the airflow on the valve member as the air flows to the multiple outlets allow for the lowest pressure drop configuration. An environmental control system (100) is designed for use with a vehicle for a plurality of uses, and the air distribution valve for use in the ducting.

L'invention concerne une soupape de distribution (10) d'air à monter dans un passage de système de conditionement d'air. La soupape de distribution d'air comprend un corps (12) doté d'une entrée (14) et de sorties multiples (16,18) qui définissent un volume (24). Le corps de soupape est prévu pour être placé dans un passage d'air d'admission. Un élément (20) de soupape assure la répartition sélective de l'air entre les différentes sorties. Des dispositifs amortisseurs (34, 36) conçus pour atténuer l'effet déstabilisant du débit d'air sur l'élément de soupape lorsque l'air va aux sorties multiples permettent de réduire au minimum la chute de pression. L'invention porte également sur un système de conditionnement d'air (100) destiné à un véhicule pour divers usages ainsi que sur la soupape de distribution d'air destinée à être utilisée dans les canalisations.
