Abstract

L'invention concerne un dispositif d'étanchéité annulaire s'étendant autour d'un axe longitudinal et destiné à être monté autour d'un arbre d'une turbomachine, le dispositif comprenant un corps annulaire (46) à l'intérieur duquel est monté un anneau formé d'une pluralité de segments carbone maintenus ensemble par des premiers moyens élastiques (62) entourant lesdits segments, des seconds moyens élastiques (64) étant intercalés longitudinalement entre une paroi annulaire radiale (57) du corps annulaire (42) et les segments carbone. Selon l'invention, les premiers moyens élastiques (62) comprennent un jonc annulaire fendu élastiquement déformable entourant lesdits segments et/ou en ce que les seconds moyens élastiques comprennent une rondelle élastique (64) coaxiale à l'axe longitudinal et élastiquement déformable en direction longitudinale.The invention relates to an annular sealing device extending around a longitudinal axis and intended to be mounted around a shaft of a turbomachine, the device comprising an annular body (46) inside which is mounted a ring formed of a plurality of carbon segments held together by first elastic means (62) surrounding said segments, second elastic means (64) being interposed longitudinally between a radial annular wall (57) of the annular body (42) and the carbon segments. According to the invention, the first elastic means (62) comprise an elastically deformable split annular ring surrounding said segments and / or in that the second elastic means comprise an elastic washer (64) coaxial with the longitudinal axis and elastically deformable in the direction longitudinal.
