  "textContent": "The chamber has a combustion chamber wall (29) at which combustion chamber shingles (30) are fixed by a bolt (31). A percussion cooling hole (32) is formed in a fastening region of the bolt in the wall, where a central axis (33) of the hole is inclined toward a central axis (34) of the bolt and forms a cross-section circular or ellipse-torus-shaped transition region (35) between the bolt and one of the shingles. The bolt is formed in a form of a threaded bolt cast on to the shingle, and in a form of a screw, which is threaded into an internal thread of a thickened area of the shingle.",
