20130343879 | TURBINE COMPRISING A SEALING DEVICE BETWEEN THE STATOR BLADE CARRIER AND THE HOUSING - The invention relates to a turbine of a power plant, having a stator, which has a housing and in the housing at least one stator blade carrier comprising stator blades. A rotor is provided which has a rotor shaft having rotor blades. At least one sealing device is provided which axially seals the respective stator blade carrier with respect to the housing and separates two regions having different pressures from one another. Improved sealing action is achieved in that the sealing device includes an axially acting primary sealing ring extending in the circumferential direction, and an axially acting additional sealing ring extending in the circumferential direction. The primary sealing ring facing the region has the lower pressure. The additional sealing ring facing the region has the higher pressure. The primary sealing ring is attached axially rigidly on the stator blade carrier. The additional sealing ring is attached axially movably, wherein the additional sealing ring is tensioned axially in the direction of the region having the higher pressure by means of at least one spring element. | 12-26-2013 |
