Abstract

Une méthode pour former un stator Moineau. Une première étape consiste à placer un tube dans un accessoire d'hydroformage. Une deuxième étape consiste à former le tube de manière à ce qu'il ait des lobes selon un processus d'hydroformage. Les lobes sont disposés selon une configuration adaptée pour interagir avec un rotor.
