Patent ID: 7850416

Claim:
A turbo-machine ( 1 ), including: a stator ( 2 ), internally coated with a running-in layer ( 6 ), the stator having a surface ( 3 ) dimensioned for close passage of a rotor, this surface ( 3 ) having an axis of symmetry and coated with said running-in layer, a rotor ( 4 ) configured for rotation within the stator ( 2 ), the rotor having an axis of rotation and having rotor blades ( 5 ) configured for close passage to said stator surface ( 3 ), and a device on which the rotor is mounted for radial displacement and rotation of the rotation axis of the rotor ( 10 ) about the axis of symmetry of the stator ( 2 ), resulting in the rotation axis of the rotor orbiting about the axis of symmetry of the stator ( 2 ) for at least partially wearing away or abrading said running-in layer.
