Patent ID: 7631501

Claim:
A gas turbine combustor comprising a sealing body for sealing an outer component with respect to an inner component, the outer component having a passage opening, through which the inner component projects out of the outer component, the outer component comprises a burner of a combustion chamber of the gas turbine, with the passage opening being formed at a head of the burner, and the inner component comprises a lance which projects from the burner head into the burner to introduce fuel into the burner and/or into the combustion chamber; the sealing body, in the installed state, being arranged in the region of the passage opening, surrounding the inner component in a circumferentially continuous manner, and bearing in a circumferentially continuous manner, by means of an inner sealing zone, against an outer sealing surface of the inner component and also bearing in a circumferentially continuous manner, by means of an outer sealing zone, against an inner sealing surface of the outer component, and the sealing body being produced by deformation from at least one metal sheet that is in strip form and is circumferentially continuous, wherein the inner sealing zone and the outer sealing zone being formed at a profiled section of the sealing body along the entire circumference, the profiled section has a spring section which yields resiliently inward and presses the outer sealing zone onto the inner sealing surface in the installed state, the spring section comprises a supporting zone bearing against the inner sealing surface of the outer component and is supported via said supporting zone against the inner sealing surface, the inner sealing zone and the outer sealing zone are formed in a holding zone, wherein the sealing body is fixed in a self-retaining manner, by means of the holding zone against a holding region of the inner component, the holding zone being formed on the profiled section at least in a circumferential section as a C-shaped clip which has two holding sections which are angled off inward, lie opposite on another and, in the installed state, engage around the holding region which is formed as an outwardly protruding holding collar.
