Abstract

A dry gas seal of a turbomachine, more particularly of a turbocompressor, for sealing a rotor-side component of the turbomachine with respect to a stator-side component of the turbomachine, having a sealing device and a support device for a stator-side sealing element of the sealing device, which can be elastically deformed.

Claims (28)

1 .- 8 . (canceled)

9 . A dry gas seal of a turbomachine, configured to seal a rotor-side component of the turbomachine relative to a stator-side component of the turbomachine, comprising:

a sealing device;

a stator-side sealing element of the sealing device; and

an elastically deformable support device for the stator-side sealing element.

10 . The dry gas seal according to claim 9 , wherein the elastically deformable support device is bellows-like.

11 . The dry gas seal according to claim 10 , wherein the elastically deformable support device is a one-piece bellows.

12 . The dry gas seal according to claim 9 , wherein the elastically deformable support device is elastically deformable in an axial direction of the rotor-side component.

13 . The dry gas seal according to claim 9 ,

wherein the elastically deformable support device is non-rotationally fastened to the stator-side component by a first section, and

wherein the elastically deformable support device carries the stator-side sealing element of the sealing device by a second section located opposite the first section,

wherein the stator-side sealing element interacts with a rotor-side sealing element of the sealing device.

14 . The dry gas seal according to claim 13 , wherein the elastically deformable support device between the first section and the second section is bellows-like.

15 . The dry gas seal according to claim 13 , wherein the elastically deformable support device pushes the stator-side sealing element of the sealing device against the rotor-side sealing element of the sealing device.

16 . A turbomachine configured as a turbocompressor, comprising:

a stator;

a rotor mounted in the stator; and

a dry gas seal for sealing the rotor relative to the stator, comprising:

a sealing device;

a stator-side sealing element of the sealing device; and

an elastically deformable support device for the stator-side sealing element.

17 . The dry gas seal according to claim 9 , wherein the turbomachine is a turbocompressor.

18 . The dry gas seal according to claim 11 , wherein the elastically deformable support device is elastically deformable in an axial direction of the rotor-side component.

19 . The dry gas seal according to claim 18 ,

wherein the elastically deformable support device is non-rotationally fastened to the stator-side component by a first section, and

wherein the elastically deformable support device carries the stator-side sealing element of the sealing device by a second section located opposite the first section,

wherein the stator-side sealing element interacts with a rotor-side sealing element of the sealing device.

20 . The dry gas seal according to claim 14 , wherein the elastically deformable support device pushes the stator-side sealing element of the sealing device against the rotor-side sealing element of the sealing device.
