Abstract
A casing body for a hot gas flow includes an outer casing body having a hot gas side with a precisely prepared locating surface. A pin-type retainer is disposed on the locating surface, and an inner heat shield is disposed at a distance from the hot gas side of the outer casing body and fastened to the retainer.
Claims18
A casing body for a hot gas flow comprising:
- an outer casing body having a hot gas side;
- a segmented inner heat shield;
- a countersink disposed on the hot gas side and a precisely prepared sunken locating surface disposed in the countersink;
- a pin-type retainer disposed on the sunken locating surface, the retainer including a separate spacer disposed on the sunken locating surface and extending from the hot gas side, the spacer including a first abutment surface abutting the sunken location surface and a second abutment surface;
- a fixing element clamping the inner heat shield and the outer casing body to one another such as to fix the spacer and to clamp the inner heat shield to the second abutment surface;
- and
- wherein the inner heat shield is clamped on the second abutment surface between a first disk and a second disk, the first disk and the second disk each having an opening, the openings receiving the spacer.

- wherein the inner heat shield is clamped on the second abutment surface between a first disk and a second disk;
- wherein the spacer comprises at an end facing away from the locating surface and above a flange on which the second abutment surface is provided, a protrusion, wherein the protrusion has a non-circular cross section, and each of the first and second disks each has a corresponding non-circular opening, said openings receiving the protrusion, such as to rotationally fix the disks on the spacer;
- and
- wherein a length of the protrusion which has the non-circular cross section is smaller than a sum of thicknesses of the first and second disks and the segment of the heat shield.
