Abstract

La présente invention concerne un ensemble pompe et un compresseur à rotor augmentant l'enthalpie, l'ensemble pompe comprenant un cylindre (100), un arbre rotatif intégré (200), un premier palier, un second palier et un canal de remplissage de gaz combiné. Le canal de remplissage de gaz combiné comprend un trou d'introduction de gaz (510) formé dans le premier palier ou le second palier, un premier canal de remplissage de gaz formé dans une face d'extrémité d'étanchéité du premier palier ou du second palier, et un second canal de remplissage de gaz formé dans une face d'extrémité d'une partie excentrique de l'arbre rotatif intégré (200). Uniquement lorsque l'arbre rotatif intégré (200) se met en rotation dans une première plage prédéfinie, toutes les parties du canal de remplissage de gaz combiné sont en communication les unes avec les autres en même temps pour former un passage à partir du trou d'introduction de gaz (510) vers une cavité de compression. Lorsque l'arbre rotatif intégré (200) se met en rotation à d'autres angles différents de la première plage prédéfinie, le canal de remplissage de gaz combiné est déconnecté. La commande de la communication et de la déconnexion du canal de remplissage de gaz combiné est réalisée au moyen de la commande du changement de l'état de communication de toutes les parties du canal de remplissage de gaz combiné, de telle sorte que les moments de début et de fin et la quantité de remplissage de gaz dans un processus de remplissage de gaz sont commandés, ce qui permet d'améliorer le remplissage de gaz et l'efficacité d'augmentation d'enthalpie du compresseur.
