Abstract

A rotation device including first and second passages and a rotor shaft with a rotor which connects onto the first passage with a third passage which branches into rotor channels from the third to a fourth passage. The end zones of the third and fourth passages extend axially. The rotation device has a stator including a first central body with an outer surface which co-bounds a passage space with stator blades which have on one end zone forming a fifth passage a direction differing from the axial direction and on another end zone forming a sixth passage a direction differing little from the axial direction. The fifth passage connects onto the fourth passage and the sixth passage connects onto the second passage. The stator includes a second central body where between the sixth passage and the second passage extend manifold channels bounded by the second central body and the housing.
