Abstract

OPTIMISATION DE LA PRESSURISATION D’UNE ENCEINTE DE PALIER DE TURBOMACHINE L’invention concerne un dispositif de pressurisation d’une l’enceinte de turbomachine ayant un axe longitudinal X, le dispositif de pressurisation s’étendant, de l’amont vers l’aval dans un sens d’écoulement des gaz le long de l’axe X longitudinal et étant alimenté en air pressurisé par un flux d’air de pressurisation (F) prélevé en amont dans la turbomachine. Selon l’invention, le dispositif de pressurisation comporte : un tourillon amont (T1) destiné à être mis en rotation autour de l’axe X et dans lequel est ménagée une première série d’ouvertures (O1), un tourillon aval destiné à être mis en rotation autour de l’axe X et dans lequel est ménagée une deuxième série d’ouvertures (O2), la première série d’ouvertures (O1) étant configurée de manière que le flux d’air de pressurisation (F) la traverse et chaque ouverture (O1) de la première série d’ouvertures (O1) étant ménagée respectivement dans une cheminée (12) insérée dans le tourillon amont (T1) Figure pour l’abrégé : figure 2OPTIMIZATION OF THE PRESSURIZATION OF A TURBOMACHINE BEARING ENCLOSURE The invention relates to a device for pressurizing a turbomachine enclosure having a longitudinal axis X, the pressurization device extending, from upstream to downstream in a gas flow direction along the longitudinal axis X and being supplied with pressurized air by a flow of pressurizing air (F) taken from upstream in the turbomachine. According to the invention, the pressurization device comprises: an upstream trunnion (T1) intended to be rotated about the X axis and in which a first series of openings (O1) is formed, a downstream trunnion intended to be rotated about the X axis and in which a second series of openings (O2) is provided, the first series of openings (O1) being configured so that the pressurizing air flow (F) passes through it and each opening (O1) of the first series of openings (O1) being provided respectively in a chimney (12) inserted in the upstream trunnion (T1) Figure for the abstract: Figure 2
