Zusammenfassung:	The invention relates to a rotary shaft device (3) comprising a housing (300), a rotary shaft (100) rotatably mounted relative to the housing (300), a pressurizing member (700) radially disposed between a main body of the rotary shaft (100) and the housing (300), said pressurizing member (700) and the main body of the rotary shaft (100) defining therebetween a pressurizing reservoir (900) configured to receive a volume of a cooling fluid; and at least one cooling channel (150) extending between a fluid inlet (151) and a fluid outlet (153), and having at least one component along the axis of rotation (X), the at least one cooling channel (150) being in fluid communication, at the fluid inlet (151), with the pressurizing reservoir (900). L'invention concerne un dispositif à arbre rotatif (3) comprenant un boitier (300), un arbre rotatif (100) monté à rotation par rapport au boitier (300), un organe de pressurisation (700) radialement disposé entre un corps principal de l'arbre rotatif (100) et le boitier (300), ledit organe de pressurisation (700) et le corps principal de l'arbre rotatif (100) définissant entre eux un réservoir de pressurisation (900) configuré pour recevoir un volume d'un fluide de refroidissement; et au moins un canal de refroidissement (150) s'étendant entre une entrée de fluide (151) et une sortie de fluide (153), et présentant au moins une composante suivant l'axe de rotation (X), l'au moins un canal de refroidissement (150) étant en communication fluidique, au niveau de l'entrée de fluide (151), avec le réservoir de pressurisation (900).
