Abstract
L'invention concerne une valve à utiliser dans un système fluidique pneumatique, notamment un système de freinage aérodynamique. Cette valve permet une libération rapide de fluide pneumatique à partir de la cavité distributrice (26) par le port de sortie (46), lors de l'arrêt du flux provenant du réservoir fluidique pneumatique et traversant la cavité de réserve (24). La valve comprend une soupape distributrice (20) permettant de restreindre l'écoulement du fluide de la cavité distributrice (26) à la cavité de réserve (24), lorsque la pression fluidique pneumatique de la cavité de réserve (34) est inférieure à celle de la cavité distributrice (26) ; et permettant une restriction minimale d'écoulement de la cavité de réserve (24) à la cavité distributrice (26), lorsque la pression dans la cavité de réserve (24) est supérieure à celle de la cavité distributrice (26).
