Abstract
A cooling arrangement () for supplying a first cavity () with a cooling gas, in particular in a gas turbine of a power plant, includes a cooling-gas passage () which is formed in a first component () and connects the first cavity () to a second cavity (). A second component () bears against a bearing side () remote from the second cavity () and separates the first cavity () from a third cavity (). The second component () is displaceable within a range of displacement. To improve the cooling effect, an orifice region () of the cooling-gas passage () is dimensioned and/or positioned in such a way that its orifice cross section () projects from the range of displacement to such an extent that it is open at least with a predetermined minimum cross section in any position of the second component ().
