Abstract

La présente invention propose un dispositif de compression (1) comprenant au moins : - deux spirales (3, 5) intercalées et formées chacune d'un alliage d'aluminium, l'une des spirales, dite spirale fixe (3), étant fixe et l'autre spirale, dite spirale mobile (5), se déplaçant excentriquement sans tourner, et -des moyens d'anti-rotation formés d'un alliage d'aluminium et adaptés pour permettre l'anti-rotation de la spirale mobile (5), caractérisé en ce qu'il comprend, en outre, au moins : - une butée plane (7) adaptée pour maintenir axialement la spirale mobile (5) et formée dans un matériau choisi dans un ensemble de matériaux comprenant les alliages d'aluminium ou les nuances de fonte, et - des revêtements adaptés pour favoriser des frottements entre la spirale fixe (3), la spirale mobile (5), les moyens d'anti-rotation et la butée plane (7).
