The invention relates to a self-adjusting device (25) for controlling the clearance (C), especially in radial direction, between rotating and stationary components (21, 23) of a thermally loaded turbo machine, which clearance (C) changes in a linear and/or non-linear way during transition of the machine between standstill and steady-state operation. A simple and effective control is achieved even in the case of a nonlinear variation of the clearance during transitional operation by said self-adjusting device (25) comprising at least two different driving elements (A, B) to move the rotating and fixed components (21, 23) relative to each other in order to change the clearance (C) between them, and by the different driving elements (A, B) being configured to be activated at different times during the transition of the machine. |
