Abstract

Machine hydraulique à engrenage, pouvant assumer la fonction d'une pompe ou d'un moteur. Elle comporte un stator à denture intérieure, comprenant une paroi intérieure qui présente plusieurs logements arrondis, espacés circonférentiellement et intercalés avec des encoches. Chaque logement reçoit un rouleau mobile radialement et circonférentiellement. Les parois des encoches peuvent fléchir élastiquement sous la pression des rouleaux en fonction des forces exercées sur ces derniers suivant que les chambres délimitées entre les éléments à denture intérieure et à denture extérieure sont soumises à une haute pression ou à une basse pression. Domaine d'application : pompes et moteurs à engrenage.
