Abstract
A liquid ring pump including at least one drive unit is described, having a drive shaft, a working space housing with an impeller rotating in it and axially freely movable on the drive shaft, and a disk cam with passages in the region of a front face of the drive shaft for an exchange of operating fluid for venting. The passage for the exchange of operating fluid and the axial free mobility have the effect that the impeller adjusts itself during operation.
