A sealing device (1) is disclosed for sealing a radially inner gas channel (2) between a guide vane ring (4) and a rotor (6) of a turbomachine, wherein the sealing device (1) has a sealing ring (8) for forming a sealed space (10) with a rear segment, with an inner wall structure (30) oriented in the opposite direction, which are joined to each other via an annular arch (32), wherein the radial flange (18) transitions into the outer wall structure (28) and the cylinder (26) forms the sealing ring (8), wherein the inner wall structure (30) transitions, via an annular web (36), into at least one inner body segment (38, 50), wherein the sealing device (1) has a uniform, preferably relatively reduced wall thickness over its individual segments integrally formed with one another, so that the sealing device (1) is resilient within certain limits. |

1. A sealing device (1) for sealing a radially inner gas channel (2) between a guide vane ring (4) and a rotor (6) of a turbomachine, wherein the sealing device (1) has a sealing ring (8) for forming a sealed space (10) with a rear segment, when considered in the direction of a principal flow, of an integral inner ring (12) of the guide vane ring (4), into which penetrates a front platform overhang (14) of a downstream row of rotating blades (16), and wherein the sealing device (1) has an outer radial flange (18) for connecting to the integral inner ring (12) and a double-walled cylinder (26) with an outer wall structure (28) oriented in a first direction and with an inner wall structure (30) oriented in the opposite direction, which are joined to each other via an annular arch (32), wherein the radial flange (18) transitions into the outer wall structure (28) and the cylinder (26) forms the sealing ring (8),
wherein the inner wall structure (30) transitions, via an annular web (36), into at least one inner body segment (38, 50), which is oriented parallel to the first direction or to the opposite direction, for the radially inner uptake of a sealing structure (40), wherein the sealing device (1) has a uniform, preferably relatively reduced wall thickness over its individual segments integrally formed with one another, so that the sealing device (1) is resilient within certain limits, wherein, in particular, the annular arch (32) and the annular web (36) act as radial spring elements. |
