Abstract (en)
The brush (10) has an axial-inflow impulse turbine placed in a secondary airstream area of a vacuum cleaner. A guide stage includes guide surfaces, where each guide surface with a cross section includes a circular arc followed by a straight section along direction of incident flow. A bearing housing surrounds a turbine shaft, where the bearing housing forms a transition and the guide stage in a region of an impeller. The bearing housing provides a casing for the turbine shaft, and includes bearing elements that support the turbine shaft.
