| 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 ).
