Beschreibung
Zusammenfassung:	A compressor wheel of a charging device may include a hub, a plurality of blades and a wheel back. The wheel back may have an undulating profile which extends from the hub in a radial direction. The undulating profile may include a plurality of regions. The plurality of regions may adjoin one another and may include a first concave region, a second convex region, a third concave region, and a fourth convex region. The second convex region may adjoin the first concave region. The third concave region may adjoin the second convex region. The fourth convex region may adjoin the third concave region.
