Abstract:
1. A sealing assembly comprising a first and second adjacent structural component part ( 4 , 6 ) of a flow machine which in an installed position are movable relative to one another about an axis; a plurality of sealing segments ( 10 , 12 ), each sealing segment comprising a central web ( 18 ) and first and second sealing bodies ( 14 , 16 ) having a circular cross-section connected to one another by said central web ( 18 ), said central web ( 18 ) comprising a unitary surface that defines a substantially flat plane extending in the axial direction and between said opposed circular first and second sealing bodies ( 14 , 16 ), said central web having a thickness and a length in the axial direction, said axial length being larger than said thickness; said structural component parts of a flow machine each having a U-shaped, rectangular longitudinal recess ( 20 , 22 ) therein; said first circular sealing body ( 14 ) being in contact only with said U-shaped recess of said first structural part ( 4 ) and said second circular sealing body ( 16 ) being in contact only with said U-shaped recess of said second structural part ( 6 ) so that each of said first and second sealing body ( 14 , 16 ) is contactingly arranged in an articulated manner only in a respective one of said U-shaped recesses ( 20 , 22 ) of said first and second structural component parts ( 4 , 6 ); a circular connection element ( 54 , 56 ) extending through each of said first and second circular sealing bodies thereby connecting said plurality of sealing segments and wherein said sealing bodies ( 14 , 16 ) and said recesses ( 20 , 22 ) are constructed to form a sliding bearing.
