Abstract
The present invention relates to a radial blade wheel () with blades (), a first wall () connected with the blades and having an opening () for enabling a flow through the wall () to the blades (), and a second wall () connected with the blades (), by which the radial blade wheel () may be connected with an apparatus rotating it. To achieve a higher efficiency, the protrusion of the blades () in the radial direction diminishes at intervals from the first wall () towards the second wall ().
