Abstract
L'invention concerne un élément d'étanchéité annulaire pour un compresseur qui peut présenter une propriété de faible couple fiable sans nuire à la durabilité ni provoquer une détérioration d'une fonction d'étanchéité. Dans un compresseur à spirale comprenant un corps fixe (3), un corps mobile (4), un arbre (7), un palier principal (9) qui supporte en rotation l'arbre (7), et un élément (12) de palier principal qui fixe le palier principal (9), conjointement avec un fluide comprimé dans une chambre de compression (5) par la rotation de l'arbre (7) amenant le corps de spirale mobile (4) à tourner autour de l'axe du corps de spirale fixe (3), le fluide est acheminé vers une chambre de contre-pression (15a) sur le côté de surface arrière du corps de spirale mobile (4), cet élément d'étanchéité annulaire (16) est monté sur au moins une rainure annulaire (4d) formée dans la surface arrière d'une partie de plaque inférieure (4a) de la spirale mobile (4), et scelle hermétiquement la chambre de contre-pression (15a). Dans une surface latérale annulaire de l'élément d'étanchéité annulaire (16), une rainure de pression dynamique est ménagée dans au moins une surface coulissante qui tourne et coulisse.
