    摘要： A gas turbine (1), with a fixed inner housing (37), arranged concentric to the rotor (3), with a throughflow of working medium, is disclosed. The housing comprises at least two serial rings (25, 26) with an annular gap (23) left between two directly adjacent rings (25, 26), whereby an annular sealing means is arranged in at least one peripheral groove (31) for sealing the annular gap (23). According to the invention, a sealing means is provided which permits a greater movement of both components forming the gap, whereby the annular gap (23) is formed by partly overlapping rings (25, 26), running against the flow direction of the working fluid (20) in the radial sense and the frontmost of the two rings (25), in the sense of the flow direction, comprises a locating annular surface (32) for the sealing means embodied as an annular spring element (24) on which the spring element (24) rests under tension such as to seal the annular gap (23).

    摘要： The invention pertains to a sealing element (1) for sealing a gap (5) which can form between two components (2a, 2b) liable to move relative to one another as a result of thermal action and each provided with an opposing groove (3a, 3b). The sealing element (1) in one cross-section is substantially perpendicular to a main line (21) along a median line (4). It has a first end (6a), a second end (6b) opposite the first end, and a central region (10) between the two ends, and is provided with teeth. The sealing element (1) is especially suitable for use in sealing a gap (5) between guide vanes (12) at high temperatures in a gas-turbine facility (22) as a means of preventing gas flow from a cool gas region (8) to a hot gas region (11).
