In a turbo engine of radial type, for example a radial compressor, diffusers (11, 12, 13) joined onto the periphery of the rotors (5, 6, 7) are provided, which comprise two parallel, annular outer discs (14, 15) with guide vanes (16) lying between them. In order to prevent sympathetic vibrations in operation and to improve the strength, especially in order to prevent weak points, for example weld seams, screw fastenings etc., the guide vanes 16 are loosely inserted in slots of the one outer plate with a certain play so that they perform more or less uncontrolled movements and cannot start to resonate owing to the high damping. <IMAGE>
