Beschreibung
Zusammenfassung:	The invention relates to a radial compressor unit for compressing gas having several compressor stages (11), wherein each compressor stage (11) comprises an impeller (18) having rotor blades (23), a flow channel (24) arranged downstream of the impeller (18) as viewed in the flow direction of the gas to be compressed, having a diffusor section (25), a deflection section (26), and a recirculation section (27) having guide blades (28). The gas compressed in a compressor stage (11) can be removed as cooling gas for cooling a component to be cooled, and can be conveyed in the direction of the component to be cooled, wherein the cooling gas can be removed adjacent to an intermediate wall (32) of the compressor stage from the deflection section (26) and/or the recirculation section (27) of the flow channel (24) of the compressor stage (11).
