A screened rotor of turbo-machine with automated control of heat exchange has a shaft, connected in periphery by labyrinth spacers discs with hubs, screen with additional cylindrical sections at both sides of the disc, shifted to back surface of disc ejection passages, supply passages as cavities and through cylindrical openings at periphery of the screen and movable tabs made of thermo-sensitive material. The movable tabs made of thermo-sensitive material are placed on the upper and the lower surfaces of ejection passages in whole inner perimeter of the screen with possibility of synchronous bend of those in direction towards axis of rotation of the rotor.
