Guide device for fluid energy machine, particularly exhaust gas turbocharger, comprises inner ring and outer ring surrounding inner ring from outer peripheral side, where inner ring and outer ring are rotatable around rotation axis

摘要

The guide device (12) comprises an inner ring and an outer ring surrounding the inner ring from outer peripheral side. The inner ring and outer ring are rotatable around a rotation axis corresponding to each other. The through-holes (28,36) are formed to allow flow-through of the rings by a medium, particularly gas in a radial direction (29) in the corresponding lateral surfaces (30) of the rings.
