Abstract

a. L'invention concerne une valve de freinage assurant un réglage de haute qualité de la vitesse, indépendamment de la charge, de consommateurs de fluide sous pression à double alimentation chargés par traction. b. Cette valve est caractérisée en ce que des étranglements de mesure sont disposés dans les conduites d'alimentation, un étranglement composite étant disposé dans une conduite de dérivation allant à un piston étagé commandant un étranglement principal et chargé par un ressort dans la direction de fermeture de cet étranglement. c. L'invention est applicable aux appareils commandés par fluide sous pression et chargés par traction.
