Abstract (en)
[origin: EP2218918A1] The compressor (1) has a stator vane grid (2) formed of stator vanes with vane tips (4) exposed on a hub side, and a stationary shaft cover (6). The cover is arranged immediately next to the tips on the hub side and delimits a flow channel of the compressor. A gap is formed between the cover and the vane tips and minimally dimensioned. Recesses (7) are formed in the cover and allocated to respective vane tips. Each recess is arranged directly neighboring the tip and dimensioned such that each tip is plunged into the recess without contacting the cover during operation of compressor.
