A heat shield arrangement for local separation of a flow channel within a turbine engine, with respect to a stator housing radially surrounding the flow channel is provided. The heat shield includes two axially opposite joining contours which are each engageable with two components which are axially adjacent along the flow channel. Each provides a complementary reception contour for the joining contours. At least one of the reception contours has an axial clearance, in which the associated joining contour is axially displaceably mounted. At least one seal is provided between the axially displaceable joining contour and the reception contour. The seal is mounted movably within the reception contour or the joining contour in such a way that the seal is deflectable against a surface region of the reception contour or of the joining contour.

What is claimed is: 1. A heat shield arrangement for local separation of a flow channel within a turbine engine, with respect to a stator housing radially surrounding the flow channel, the heat shield comprising two axially opposite joining contours which are each engageable with two components which are axially adjacent along the flow channel and which each provide a complementary reception contour for the joining contours, at least one of the reception contours has an axial clearance, in which the associated joining contour is axially displaceably mounted, at least one seal being provided between the axially displaceable joining contour and the reception contour, the seal is mounted movably within the reception contour or the joining contour in such a way that the seal is deflected against a surface region of at least one of the reception contour or of the joining contour, the joining contour including a joining face in which is introduced for the seal a recess out of which the seal is deflectable so as to project partially beyond the joining face into a gap defined between the reception contour surface region and the joining face. 2. The heat shield as claimed in claim 1, wherein at least one of the reception contour or the joining contour has a joining face in which is introduced for the seal a recess out of which the seal is deflectable so as to project partially beyond the joining face. 3. The heat shield as claimed in claim 2, wherein at least one spring element, that deflects the seal by the action of spring force, is provided in the recess. 4. The heat shield as claimed in claim 3, wherein the at least one spring element is designed as a curved bar spring and is held in the longitudinal direction with respect to the recess. 5. The heat shield as claimed in claim 3, wherein the recess has a radially oriented boundary face which consists of a sealing material, the seal has a radially upper side edge which is adapted to the surface region against which the seal can be pressed, and the seal has a radially lower sloped side edge, against which the spring element presses, and an inclination of the slope is selected in such a way that the seal can be pressed both against the surface region and against the boundary face consisting of the sealing material. 6. The heat shield as claimed in claim 3, wherein the seal is comprised of a metallic material. 7. The heat shield as claimed in claim 3, wherein the seal is an incompressible solid body. 8. The heat shield as claimed in claim 3, wherein the seal is bar-shaped and has a local protrusion along its extent, and the joining contour comprises a recess, which is adapted to the protrusion and along which the protrusion is guided in the radial direction, is provided in the recess. 9. The heat shield as claimed in claim 2, wherein the seal is bar-shaped and has a local protrusion along its extent, and the joining contour comprises a recess, which is adapted to the protrusion and along which the protrusion is guided in the radial direction, is provided in the recess. 10. The heat shield as claimed in claim 2, wherein the seal deflectable by spring force against the surface region of at least one of the reception contour or of the joining contour. 11. The heat shield as claimed in claim 2, wherein the seal is comprised of a metallic material. 12. The heat shield as claimed in claim 2, wherein the seal is an incompressible solid body. 13. The heat shield as claimed in claim 1, wherein the seal deflectable by spring force against the surface region of at least one of the reception contour or of the joining contour. 14. The heat shield as claimed in claim 13, wherein at least one spring element, that deflects the seal by the action of spring force, is provided in the recess. 15. The heat shield as claimed in claim 13, wherein the seal is comprised of a metallic material. 16. The heat shield as claimed in claim 13, wherein the seal is an incompressible solid body. 17. The heat shield as claimed in claim 13, wherein the seal is bar-shaped and has a local protrusion along its extent, and the joining contour comprises a recess, which is adapted to the protrusion and along which the protrusion is guided in the radial direction, is provided in the recess. 18. The heat shield as claimed in claim 1, wherein the seal is comprised of a metallic material. 19. The heat shield as claimed in claim 18, wherein the seal is an incompressible solid body. 20. The heat shield as claimed in claim 1, wherein the seal is an incompressible solid body.
