摘要
The wall section (14) has a guide ring (26) arranged in a peripheral groove (24) and limiting a circular flow channel (10). The guide ring is movable for adjusting a radial gap in an axial direction. The radial gap is provided between a wall surface (28) of the guide ring and a moving blade tip (30) lying opposite to the wall surface. The guide ring comprises a tooth (50) at a front side, where the tooth rests against another tooth (46) arranged at a side wall (27) of the peripheral groove. The guide ring is rotated in a circumferential direction for axial shifting of the guide ring.
