Gap seal in a gas turbine
View Patent ↗A gap seal in a gas turbine for sealing off a cooling space, formed between a heat shield and a heat shield carrier, from a hot gas space of the gas turbine. A sealing body is retained in a movable manner on the heat shield, on the one hand, and on a blade carrier, on the other hand, adjacent to the heat shield carrier.
1. A gap seal in claim 1 in a gas turbine for sealing off a cooling space formed between a heat shield and a heat shield carrier, from a hot gas space of the gas turbine, comprising: a sealing body which is retained in a movable manner between the heat shield and a blade carrier, wherein a gap formed axially between the heat shield carrier and the blade carrier, in a section which is sealed off from the hot gas space by the sealing body, forms a flow path for the cooling gas recirculation.
2. A gap seal in a gas turbine for sealing off a cooling space formed between a heat shield and a heat shield carrier, from a hot gas space of the gas turbine, comprising: a sealing body which is retained in a movable manner between the heat shield and a blade carrier, wherein the heat shield has first and second grooves which are open toward the heat shield carrier and into which the sealing body with its side assigned to the heat shield, is inserter, the blade carrier having a collar which projects axially toward the heat shield carrier and in which a locating groove of the blade carrier is formed, and wherein the heat shield carrier has an axial recess into which the collar projects.
