OUTFLOW REGION OF A COMPRESSOR, COMPRESSOR HAVING AN OUTFLOW REGION OF SAID TYPE, AND TURBOCHARGER HAVING THE COMPRESSOR

摘要

The invention relates to an outflow region (10) of a compressor (20), in particular of a radial compressor or diagonal compressor. The outflow region (10) comprises a flow channel (11) which is delimited by side wall (12) at a shroud side and a side wall (13) at a hub side. The side wall (13) at the hub side has, in a region (14) of the compressor wheel outlet, a contour which is configured such that, in a flow direction (1), the cross-sectional areas of the flow channel decrease, pass through a minimum and increase again. In the region (14) of the compressor wheel outlet, the flow channel (11) has a length L which extends from a compressor wheel outlet edge (4) to a diffuser blade inlet edge of a diffuser region (16). The diffuser region (16) adjoins the region (14) of the compressor wheel outlet and has a multiplicity of diffuser blades (17). The invention furthermore relates to a compressor (20), in particular a radial compressor or diagonal compressor, with the outflow region (10) according to the invention, and to a turbocharger having the compressor (20).
