| 摘要 |
The present invention relates to a radial blade wheel (1) with blades (3), a first wall (2) connected with the blades and having an opening (4) for enabling a flow through the wall (2) to the blades (3), and a second wall (5) connected with the blades (3), by which the radial blade wheel (1) may be connected with an apparatus rotating it. To achieve a higher efficiency, the protrusion of the blades (3) in the radial direction diminishes at intervals from the first wall (2) towards the second wall (3). |
