Seal for annular sealing zone, e.g. between blade and mounting in turbine, with surfaces to be sealed at right angles to each other comprises sealing component cooperating with each surface which can be elastically deformed parallel to it

摘要

The seal for an annular sealing zone (1) between two machine components (2, 3), one of which (3) has a first sealing surface (9) parallel to a first direction (a) and a second surface (15) parallel to a direction (r) at right angles to it. A first seal (12) cooperates with the first surface and can be deformed parallel to it, A second seal (18) cooperates with the second surface and again can be deformed parallel to it. Both seals can move relative to each other without affecting the sealing properties.
