The invention relates to a turbo engine, particularly a gas turbine, comp rising a stator and a rotor. The rotor has moving blades while the stator ha s a housing (11) and guide blades (12). The moving blades of the rotor form at least one moving blade ring, each of which borders an inner ring of the s tator or outer ring (17) of the housing at a radially outward end, is surrou nded by said inner ring or outer ring (17), and delimits a gap along with th e same. The respective outer ring (17) is connected to a bearing ring (20) v ia curved walls (19) which delimit a hollow space (22) along with the outer ring (17) and the bearing ring (20) and form a bellows-type structure (21). The gap between the outer ring (17) and the radially external end of the res pective moving blade ring can be pneumatically adjusted by modifying the pre ssure prevailing in the hollow space (22) of the respective bellows-type str ucture (21). According to the invention, each wall (19) is curved exclusivel y once inward into the respective hollow space (22) from an axial perspectiv e in the area of the or each bellows-type structure (21).
