Abstract:
A sealing arrangement, comprising:a first member and an adjacent second member, the first member and the second member belonging to a rotor arrangement, wherein the second member is located radially outwardly of the first member; a flow channel extending through the first member and the second member, said flow channel having a seam at a contacting surface between the first and the second adjacent members, said seam to be sealed off during rotor rotation; the first member having a recess on the contacting surface surrounding the flow channel, the recess thus being arranged between the first and second members, a sealing member being provided in the recess; wherein the sealing member is designed and made to have a clearance with at least one of the first and second members in static conditions, and to provide a sealing contact with a least one sealing surface of each of the first and second members when centrifugal forces act due to rotation of the rotor, thus providing a sealing of the flow channel during operation, wherein the sealing effect is affected by a displacement of the sealing member in connection with at least one of an elastic deformation of the sealing member or a plastic deformation of the sealing member due to centrifugal forces acting during rotation of the rotor.
