Abstract:
The invention relates to a turbocompressor (1) comprising a compressor housing (2) and a compressor wheel (4) with blades (5). The compressor wheel (4) is rotatably mounted relative to the compressor housing (2) and is arranged such that the exposed upper edges of the blades (5) are spaced from a compressor housing (2) wall (3) facing the blade upper edges across a head gap (7), wherein both the upper edges of the blades (5) as well as the housing wall (3) have at least one recess (11, 13) and at least one elevation (10, 14) over the respective Meridian contour, said recess and elevation interacting locally such that the head gap (7) defines a Z-shaped course in the region of the recesses (11, 13) and the elevations (10, 14) when viewed on a Meridian plane.
