Abstract

Spirale pour un compresseur à spirale et un compresseur à spirale le comprenant. Le compresseur à spirale comprend une première spirale (10) et une seconde spirale (20). La seconde spirale (20) fonctionne conjointement avec la première spirale (10) pour former une cavité de compression pour une compression de milieu. La première spirale (10) est une spirale fixe et la seconde spirale (20) est une spirale orbitale. La première spirale (10) et la seconde spirale (20) comprennent chacune une plaque d'extrémité (29) et une spirale hélicoïdale (21). La spirale hélicoïdale (11) d'au moins l'une de la première spirale (10) et de la seconde spirale (20) comprend : un corps de spirale hélicoïdale (110), le corps de spirale hélicoïdale (110) comprenant une surface d'extrémité en forme de bande (111) à l'opposé de la plaque d'extrémité (19) ; et une saillie (113) s'étendant à partir de la surface d'extrémité du corps de spirale hélicoïdale (110), la saillie (113) s'étendant le long d'au moins une partie de la longueur de la surface d'extrémité du corps de spirale hélicoïdale (110). La spirale pour un compresseur à spirale et le compresseur à spirale peuvent améliorer les performances d'étanchéité entre la spirale fixe et la spirale orbitale.
