What is claimed is: 1. A tube-type vortex reducer for the conduction of cooling air in a compressor of a gas turbine with at least one radial secondary air tube arranged in a compressor disk interspace for conducting cooling air radially inwardly, comprising: a deflector positioned in a discharge area of the secondary air tube for the deflection of the secondary air flow into an axial direction, wherein the deflector comprises an essentially conical deflector ring installed on a compressor shaft. 2. A tube-type vortex reducer in accordance with claim 1, wherein an effective deflection surface of the deflector ring is orientated at essentially 45° to a center plane of a rotational axis of the compressor shaft. 3. A tube-type vortex reducer in accordance with claim 2, wherein the effective deflection surface of the deflector ring is orientated at essentially 45° to a radial center plane of the secondary air tube. 4. A tube-type vortex reducer for the conduction of cooling air in a compressor of a gas turbine with at least one radial secondary air tube arranged in a compressor disk interspace for conducting cooling air radially inwardly, comprising: a deflector positioned in a discharge area of the secondary air tube for the deflection of the secondary air flow into an axial direction wherein the deflector comprises a deflector plate attached to the secondary air tube and the deflector plate is essentially planar and oriented at essentially 45° to a radial center plane of the secondary air tube. 5. A tube-type vortex reducer for the conduction of cooling air in a compressor of a gas turbine with at least one radial secondary air tube arranged in a compressor disk interspace for conducting cooling air radially inwardly, comprising a deflector positioned in a discharge area of the secondary air tube for the deflection of substantially all of the secondary air flow in a generally same direction away from an axial direction. 6. A tube-type vortex reducer in accordance with claim 5, wherein the deflector comprises a deflector plate attached to the secondary air tube. 7. A tube-type vortex reducer in accordance with claim 6, wherein the deflector plate is essentially orientated at 45° to a radial center plane of the secondary air tube and is rotated away from an axial direction by about 90°. 8. A tube-type vortex reducer in accordance with claim 5, wherein the deflector comprises a secondary air tube outlet portion oriented at an angle to a center plane of the secondary air tube. 9. A tube-type vortex reducer in accordance with claim 8, wherein the secondary air tube outlet portion is oriented at about 90° to the center plane of the secondary air tube. 10. A tube-type vortex reducer in accordance with claim 9, wherein a discharge flow of the secondary air tube is opposite to the direction of rotation of the compressor shaft. 11. A tube-type vortex reducer in accordance with claim 8, wherein a discharge flow of the secondary air tube is opposite to the direction of rotation of the compressor shaft. 12. A tube-type vortex reducer in accordance with claim 5, wherein a discharge flow of the secondary air tube is opposite to the direction of rotation of the compressor shaft.
