Abstract

L'invention concerne un piston de compresseur. Le piston est caractérisé en ce qu'il comprend une première partie cylindrique qui est munie d'anneaux de pression, une seconde partie cylindrique disposée coaxialement à la première partie et d'un diamètre plus petit que celle-ci, ainsi qu'un fourreau cylindrique qui est emmanché de façon lâche autour de la seconde partie cylindrique et qui a essentiellement le même diamètre extérieur que la premiere partie cylindrique et en ce que le fourreau est maintenu assemblé avec la seconde partie cylindrique par au moins une bague torique interposée entre le fourreau et la seconde partie cylindrique. Application à des compresseurs.
