Abstract

La présente invention concerne un compresseur comportant un ensemble cylindre (301) ayant un espace de compression interne, un chemin d'aspiration (310) et un chemin d'évacuation raccordés à l'espace de compression, un arbre rotatif (140) inséré dans l'ensemble cylindre longitudinalement ; une plaque de séparation (150) conçue pour séparer l'espace de compression en un premier espace de compression et un second espace de compression (341, 342) et pour tourner du fait de son association à l'arbre rotatif (140) ; et une première et une seconde aube (341, 342) en contact avec chaque surface de la plaque de séparation (150) de manière à diviser le premier et le second espace de compression (341, 342) en une région de compression et une région d'aspiration respectivement aux fins de la création d'un mouvement alternatif à l'intérieur d'une région donnée, suivant la direction longitudinale de l'arbre rotatif (140), en accord avec la rotation de la plaque de séparation (150), une partie en contact avec la surface ayant une section circulaire et une courbure identiques à un diamètre externe de l'arbre rotatif (140) étant formée sur l'une au moins des première et seconde aubes (341, 342).
