摘要：In an arrangement for influencing the radial clearance of the blading of an axial-flow, highly loaded compressor which essentially comprises a rotor (1) equipped withmoving blades (2) and a blade carrier (3) which is equipped with guide blades (4) and ishung in a casing (5), the blade carrier (3) has long and narrow mountings (7) for the guideblades (4), at least one hollow space (9) being arranged in the guide- blade roots (8), ahollow space (10) being present in each case in the embedded state in the peripheraldirection between the guide-blade root (8), the two mountings (7) for a guide blade (4)and the blade carrier (3) , a further hollow space (11) being present in each case in theperipheral direction between the blade carrier (3) and the mountings (7) for two
successive guide blades (4), which hollow space (11) is defined by a plurality of segments(12) distributed over the periphery and connected to the guide- blade roots (8), and thehollow spaces (9, 10, 11) being filled with insulating material (15).
