Zusammenfassung:AN ARRANGEMENT FOR THE ADMISSION OF COOLING AIR TO THE INTERNAL WALLS OF A COMPONENT ROTATING ABOUT A ROTATION AXIS (2), IN PARTICULAR A MOVING BLADE (1) IN A ROTARY MACHINE, IS DESCRIBED, HAVING A COMPONENT ROOT WHICH CAN BE FASTENED TO A ROTOR UNIT IN A ROTATIONALLY FIXED MANNER AND ADJOINING WHICH IN ONE PIECE IN A RADIALLY EXTENDING MANNER IS A COMPONENT AIRFOIL (4) IN WHICH -AT LEAST ONE RADIALLY EXTENDING COOLING PASSAGE REGION (KL) IS PROVIDED WHICH, IN THE REGION OF THE COMPONENT ROOT (3), OPENS OUT VIA AN OPENING (7) INTO A COOLING-AIR SUPPLY PASSAGE (5) PASSING AT LEAST PARTLY THROUGH THE COMPONENT ROOT (3) LONGITUDINALLY RELATIVE TO THE ROTATION AXIS (2). THE INVENTION IS CHARACTERIZED BY THE FACT THAT A DISTRIBUTION PLATE (8) IS PROVIDED IN THE REGION OF THE COOLING-AIR SUPPLY PASSAGE (5) IN SUCH A WAY THAT THE DISTRIBUTION PLATE (8) FORMS A FLUID-TIGHL CONNECTION WITH AN OPENING MARGIN (71), SURROUNDING THE OPENING (7) OF THE COOLING PASSAGE REGION (KL) , AT LEAST DURING THE ROTATION OF THE COMPONENT ABOUT THE ROTATION AXIS (2), AND IN THAT THE DISTRIBUTION PLATE (8) PROVIDES AT LEAST ONE THROUGH-OPENING (81)IN THE REGION OF THE OPENING (7) OF THE AT LEAST ONE COOLING PASSAGE REGION (KL), THROUGH WHICH THROUGH-OPENING (81) COOLING AIR PASSES FROM THE AXIAL COOLING-AIR SUPPLY PASSAGE (5) 30 INTO THE RADIAL COOLING PASSAGE REGION (KL) .
