A device for positioning of nozzles of a stator stage and for cooling of rotor discs in gas turbines, of the type which is applicable to nozzle segments consisting of several foils (11), wherein each of the nozzle segments is connected at the top to an outer ring (12) to contain cooling air, and is positioned at the base on an inner ring (23) which makes it possible to arrange the nozzle segments circumferentially relative to the axis of the said gas turbine, and is structured such that, for each foil (11) of the nozzle segment, there is provided at least one tube (16), which is inserted in a corresponding duct (32) present inside the foils (11), which puts an area (16) where the cooling air circulates into communication with the first stage disc 20 (37) and the second stage disc (55).
