Abstract

A tube-type vortex reducer for the conduction of cooling air in a compressor 1 of a gas turbine with at least one radial secondary air tube 2 arranged in a disk interspace 3, includes a deflector arranged in a discharge area of the secondary air tube for the deflection of the secondary air flow into an axial direction or away from an axial direction.
