In a rotor (1) for thermal turbomachines, in particular a compressor part (2), center part (3) and turbine part (4) arranged on one shaft, the rotor (1) mainly consisting of individual rotary bodies welded to one another, the geometrical form of which leads to the formation of axially symmetrical ho
In a rotor (1) for thermal turbomachines, in particular a compressor part (2), center part (3) and turbine part (4) arranged on one shaft, the rotor (1) mainly consisting of individual rotary bodies welded to one another, the geometrical form of which leads to the formation of axially symmetrical hollow spaces (5) between the respectively adjacent rotary bodies, there are provided a further, cylindrical hollow space (7) extending around the center axis (6) of the rotor (1) and reaching from the downstream end of the rotor (1) up to the last hollow space (5h) upstream and at least two tubes (8, 9) having different diameters and lengths from one another, which tubes (8, 9) overlap at least partly and are placed in the cylindrical hollow space (7), in which arrangement the tubes (8, 9) are each firmly anchored to at least one fixed point and the fixed points of the tubes (8, 9) lie at axially different locations. The tubes (8, 9) are each provided with at least two through-openings (13) in the circumference, at least one opening (13) being arranged in the turbine part (4) and at least one opening (13) being arranged in the compressor part (2) or center part (3), and the openings (13) in the different tubes (8, 9) overlapping in the turbine part (4) in the hot operating state, whereas they overlap in the compressor part (2) and center part (3) in the cold state.

A rotor for thermal turbomachines, including a compressor part, center pan and turbine pan arranged on one shaft, the rotor comprising individual rotary bodies welded to one another, the geometrical form of which leads to the formation of axially symmetrical hollow spaces between the respectively adjacent rotary bodies, wherein a) a cylindrical hollow space extending around the center axis of the rotor and reaching from the downstream end of the rotor up to the last hollow space upstream is provided, b) at least two tubes having different diameters and lengths from one another and at least partly overlapping are placed in the cylindrical hollow space, c) the tubes are each firmly anchored to at least one fixed point, d) the fixed points of the tubes lie at axially different locations, e) the tubes are each provided with at least two through-openings in the circumference, at least one opening being arranged in the turbine part and at least one opening being spaced from the opening in the turbine part, and f) the openings in the different tubes overlap in the turbine pan in the hot operating state, whereas they overlap in the compressor part and center part in the cold state.
