摘要：
A spiral housing with a spiral cross-section for a turbomachine, in which a disk diffuser with an upstream annular disk space is asymmetrical to the spiral cross-section. This spiral cross-section has a base circle of substantially constant diameter. The spiral cross-section also has a tongue region and a region adjacent to the tongue with circular spiral cross-sections extending to where an outside diameter of the spiral cross-section equals a specific diameter and the circular spiral cross-sections continue thereafter to increase in cross-section only axially.
