Definitions
- Compressor rotors if possible to realize without Railunwuchten. These objects are achieved by a compressor rotor unit, hereinafter referred to only briefly as a compressor rotor, having the features according to the independent claim.
- the toothed segment at its two (axial) ends each have a toothing about which the toothing segment is held by corresponding counter teeth on (axial) ends of the impeller segment and the terminal segment axially between the impeller segment and the terminal segment.
- the invention means with "about” - to the toothing - "held corresponding counter teeth” that the toothing (at the axial end of a segment) and the counter-toothing (at the axial end of the other segment) are engaged, creating a positive connection to
- the gas seal 6 can be smaller due to the smaller outer diameter of the components of the gas seal 6.
