Abstract
A scroll machine for a medium has a machine housing having a longitudinal axis and an inlet and an outlet for the medium. Provided in the machine housing along the longitudinal axis is: a drive unit having a drive shaft mounted on the machine housing by a first bearing unit and a second bearing unit, a first spiral unit having a spiral channel formed by a first spiral rib and has an inner end region and an outer end region, and a second spiral unit having a spiral channel formed by a second spiral rib and has an inner end region and an outer end region. The first spiral unit and the second spiral unit engage one another to form pressure chambers, wherein the first spiral unit can be moved by means of the drive shaft through the drive unit along an orbital path relative to the second spiral unit.
