Sealing element for sealing a gap
View Patent ↗A sealing element for sealing a gap between two components is provided. The sealing arrangement may be a seal arrangement of a gas turbine system, wherein the sealing element is elongate along a main line and has a contoured cross section in a corrugated center region. In cross section, the sealing element is directed along the main line and may be deformed in a direction substantially orthogonally with respect to the main line. In order to provide a wear-resistant, long-lasting sealing element with a particularly efficient blocking action, it is proposed that the seal teeth of the corrugation have a virtually rectangular cross-sectional contour, the tooth height of which seal teeth is between 10% and 40% of the sealing-element thickness which may be measured parallel to the tooth height.
1. A plate-like sealing element for sealing a gap between two components, the sealing element comprising:
a central region;
a first end;
a second end; and
a first surface,
wherein the two components may be moved in relation to one another as a result of mechanical or thermal action and each have a mutually opposite component groove for accommodating the sealing element,
wherein the sealing element is directed along a main line and, as seen in a cross section essentially perpendicular to the main line,
wherein the central region is arranged between the first end and the second end,
wherein the first surface is toothed comprising sealing teeth,
wherein all the sealing teeth have an essentially rectangular cross-sectional contour and the tooth height thereof is between 10% and 40% of a thickness of the sealing element, and
wherein the thickness of the sealing element is measured parallel to the tooth height and includes the tooth height,
wherein a spacing between two directly adjacent sealing teeth is 1.6 times the average tooth height of the two sealing teeth, and
wherein the thickness of the sealing element is between 1.0 mm and 4.0 mm, and
wherein the tooth height is between 0.1 mm and 1.6 mm.
2. The sealing element as claimed in claim 1 ,
wherein the tooth height is between 0.3 mm and 0.7 mm.
