Lubrification device for a turbo machine

The invention relates to a lubrication device (1) for a turbo machine, comprising:a rotor (2) rotating around an axis,at least one lubrication chamber (6) formed in the rotor (2),a stator (22) in which the rotor (2) is rotatably mounted,a bearing (11) for rotationally guiding the rotor (2), mounted between the rotor (2) and the stator,lubricating fluid supply means which supply at least the chamber (6) and the bearing (11), the lubricating fluid supply means comprising a nozzle (23) mounted on the stator provided with an ejection nozzle (34) at a free end of the nozzle (23), said nozzle (34) being configured to project the lubricating fluid into the chamber (6),characterized in that the nozzle (23) has a movable part (27) including said ejection nozzle (34), said movable part (27) being movable between a retracted position in which the ejection nozzle (34) is remote from the chamber (6) or at least partially located outside the chamber (6), and an extended position in which the nozzle (34) is closer to the chamber (6) or at least partially located in the chamber (6).
