Abstract

The object of the invention is to create a centrifugal compressor with a cooling appliance which is simpler but more effective. This is achieved by the feed device (27) for the gaseous cooling medium (31) opening into the separating gap upstream of the mainly radially extending gap region (20) of the separating gap (18).
