Sealing configuration, in particular for a rotary machine

摘要

A sealing configuration is provided for sealing off a first region from a second region through which a fluid can flow and which can be kept at different pressures. The sealing configuration has a deformation region and a sealing surface connected thereto. The sealing surface is spaced apart from an opposing surface by a sealing gap. The width of the sealing gap depends on a deformation of the deformation region as a result of a differential pressure. The sealing configuration preferably serves to seal off a turbine shaft from a turbine casing or a moving blade from a turbine casing.
