ABSTRACT:
This compressor is provided with a compressor impeller (1) which has a hub (2) of plastic fitted with moving blades (5), with a shaft which is connected to the hub (2) and extends along an axis (4), and with a housing which surrounds the compressor impeller (1).
It is intended to provide a compressor which has a compressor impeller produced from a plastic and is nevertheless suitable for comparatively high operating temperatures. This is achieved by the hub (2) of the compressor impeller (1) being produced from a thermoplastic reinforced with continuous fibers, and by the moving blades (5, 20) being prefabricated separately from a thermoplastic reinforced with continuous fibers and connected with a form fit to the hub (2).
