Abstract

Soupape de commutation pour fluide compressible commandée par un fluide distinct, avec piston d'actionnement 9, piston d'amortissement 10 et espace de décompression 12 relié par une soupape de commande 21 à une conduite de fluide sous pression plus faible. Entre l'espace d'amortissement 13 et l'espace 12 est prévu un trajet de fuite à travers lequel, quand la soupape 21 est ouverte, la pression en 13 diminue lentement et en outre un canal de dérivation 15 est évidé dans le piston 10. Application aux soupapes à actionnement rapide.
