Abstract

Dispositif n'autorisant le mouvement de la presse que si deux tiges de soupape sont simultanément en position de travail. La soupape de commande de presse comporte deux tiges de soupape 10 et 12 associées respectivement à une soupape pilote 14, 18 présentant un enroulement 22, 24 et à un commutateur 16, 20. Les raccordements 26, 28, 30 sont respectivement en liaison avec une source de fluide, avec la presse et avec un retour.
