Patent ID: 8820748

Claim:
A sealing system for a turbomachine for sealing an annular gap between a rotor and a stator of the turbomachine, comprising: a sealing body inserted into the annular gap that bridges the annular gap and elastically compensate for a height variation of the annular gap, wherein a height of the sealing body varies correspondingly with the height variation of the annular gap; and a sealing ring that is held in the sealing body in the annular gap between the rotor and the stator to block the annular gap, wherein the sealing ring is configured to have an inner diameter that is dimensioned to maintain an inner radial clearance between the rotor and the stator during an operation of the turbomachine to prevent damage of the sealing ring in an event of a radial movement of the rotor, wherein the sealing ring is configured to have an outer diameter that is dimensioned to maintain an outer radial clearance between the rotor and the stator during an operation of the turbomachine to prevent damage of the sealing ring in the event of the radial movement of the rotor, wherein the sealing system comprises at least two sealing rings which are disposed at an axial distance from one another, and wherein the at least two sealing rings are configured to have inner diameters and outer diameters that are dimensioned differently from each other to maintain the inner radial clearance and the outer radial clearance between the rotor and the stator.
