The invention relates to a brush seal for sealing a gap between a rotor and a stator, with at least one brush ring, comprising a number of sealing brushes and at least two annular brush ring carriers, running in the circumferential direction of the rotor. Each brush ring is fixed between a first front face of a first brush ring carrier and a second front face of a second brush ring carrier, whereby the second brush ring carrier is directly axially and radially fixed to the first brush ring carrier.

The invention claimed is: 1. A brush seal for sealing a gap between a rotor and a stator, comprising: a brush ring having a multiplicity of sealing bristles, and with at least two annular brush ring carriers extending in the circumferential direction of the rotor, each brush ring being fixed between a first end face of a first brush ring carrier and a second end face of a second brush ring carrier, and the second brush ring carrier being directly fixed axially end radially to the first brush ring carrier, wherein the second brush ring carrier is fixed to the first brush ring carrier by an unrealeasable snap connection. 2. The brush seal as claimed in claim 1, wherein a slot is formed between the first brush ring carrier and the second brush ring carrier and the slot receives the brush ring. 3. The brush seal as claimed in claim 1, wherein at least one first brush ring carrier has on its first end thee a shoulder with a circumferential slot and at least one second brush ring carrier has on its second end face a continuous projection, with a latching nose, end the projection and the latching nose of the second brush ring carrier cooperates with the shoulder and with the circumferential slot of an adjacently arranged first brush ring carrier, wherein the snap connection is formed between the circumferential slot and the latching nose. 4. The brush seal as claimed in claim 3, comprising a plurality of the brush ring carriers of claim 3 adapted for sequential installation onto a stator, wherein the circumferential slot of one of the plurality of the brush ring carriers is disposed to receive the latching nose of an adjacently arranged brush ring carrier. 5. The brush seal as claimed in claim 4, wherein the circumferential slot is formed disposed toward an outside diameter of the at least one first brush ring carrier. 6. The brush seal as claimed in claim 3, wherein the circumferential slot is formed disposed toward an outside diameter of the at least one first brush ring carrier. 7. The brush seal as claimed in claim 1, wherein the second brush ring carrier has on its first end face a shoulder with a circumferential slot on its second end face a continuous projection, with a latching nose, and the projection and the latching nose of the second end face of the second brush ring carrier cooperates with a shoulder and with a circumferential slot of the first brush ring carrier. 8. The brush seal as claimed in claim 1, wherein one brush ring carrier is held at least indirectly on the stator. 9. The brush seal as claimed in claim 1, wherein the brush ring carrier or brush ring carriers have a support plate that extends in the direction of the rotor and the brush rings bear axially against the support plate. 10. The brush seal as claimed in claim 1, wherein the brush ring carrier or brush ring carriers have a protective ring. 11. The brush seal as claimed in claim 10, additionally comprising a support plate, wherein at least one of the support plate and the protective ring is or are designed to be radially elastic. 12. The brush seal as claimed in claim 1, wherein the brush seal is designed as a radial seal or axial seal.
