FIELD: machine building.
SUBSTANCE: invention relates to compressors creation. Sealing device (200) for the centrifugal compressor contains a stator (220) with socket (230) for seal, seal (223) installed in the above socket (230) and having abraded part (225) passing along the internal periphery, a rotor (210) with teeth (215) made with possibility of rotation within limits of the specified internal periphery of the seal (223), and creation of the grooves (227) in the abraded part (225), and first spring (240) between the stator (220) and seal (210) and made supporting axial movement of the seal (223) relatively to the specified socket (230).
EFFECT: invention decreases leaks between stator seal and rotor of the rotor assembly.
