Sealing arrangement between a shaft and a housing of a fluid flow engine |
摘要 |
A sealing arrangement between a shaft and a housing of a fluid flow engine consists of a blocking gas space acted upon with blocking gas, which is delimited by two sealing rings guided in annular grooves of the shaft and radially sealingly abutting at the shaft through-bore. In order to avoid operation-endangering wear of the sealing rings in case of failure of the blocking gas supply, the shaft through-bore is constructed with three diameter regions mutually offset by right angle steps. The steps form each an axial support for the coordinated sealing ring which comes into action when a permissive initial wear has occurred at the sealing ring.
