Abstract

L’invention concerne un compresseur de type pale statique comprenant un rotor (1), un cylindre (2), une pale (3), une colonne (4) de rotation et des couvercles. Le rotor est installé dans le cylindre, excentré par rapport à celui-ci. L’axe du rotor tourne autour de l’axe de cylindre. La surface externe du rotor et la surface interne du cylindre sont tangentes. L’extrémité externe de la pale est fixée sur le cylindre et ses extrémités latérales sont fixées sur les deux couvercles. Une rainure (5) circulaire est pratiquée sur le rotor. La colonne de rotation vient s’accoupler avec ladite rainure circulaire et tourne en suivant son mouvement. Sur la colonne de rotation est pratiquée une glissière (6) plate dans laquelle est introduite la pale qui glisse en suivant son mouvement. Le caractère statique du cylindre, de la pale et des couvercles d’une part permet de supprimer le jeu et les mouvements existant entre eux, et ainsi, de diminuer les dégâts provoqués par les frictions entre la pale et le cylindre, et entre la pale et les couvercles, et les dégâts provoqués par les fuites. D’autre part la pale n’étant pas un élément mobile, il n’est pas nécessaire de se soucier de l’équilibre dynamique, autrement dit, l’équilibre dynamique du compresseur est simplifié.
