Abstract: A flat shaped sealing device for sealing a gap between two parts having a sealing length and a sealing width from one side edge to the opposite side edge of at most 0.2-times the sealing length and having a sealing thickness from a bottom side to a top side of at most 0.2-times the sealing width. The sealing device includes a head section and an adjacent main section. The head section includes an abutment and a spring, wherein the abutment is displaceable towards the main section and the spring is therefore arranged between the abutment and the main section and is able to exert a force on the abutment.

Abstract: A sealing strip element for sealing a gap between two components of a gas-turbine installation, and extends along a longitudinal direction and has a contoured cross section in a ribbed central region. The sealing strip element extends along the longitudinal direction, wherein at least one of the first main surface and the second main surface includes a riffle structure, wherein the riffle structure has multiple teeth extending substantially from the first strip end to the second strip end along a substantially straight line while establishing chutes between them, wherein at least one dam is provided at at least one strip end of the sealing strip element.

Abstract: A seal for sealing a gap in a combustion apparatus of a gas turbine between a first side and an opposite second side. The seal includes a steel strap with a flat shape and a first metal web with a flat shape attached to the steel strap on the first side and a second metal web attached to the steel strap on the second side. Thereby the seal has a seal thickness with at least the steel strap plus the first metal web plus the thickness of the second metal web, wherein the seal thickness is at most 0.2-times of width of the seal. The new seal has an Omega shape of the second metal web, which is therefore attached on both sides with a flat shaped portion to the steel strap.
