Impeller wheel for side channel machine, e.g. compressors and vacuum pumps, has at least one guide rib between adjacent blades extending inwards into cross-sectional region(s) of radial outer edging of flow chamber

摘要

The device (1) has blades (3) arranged at intervals in the peripheral direction and intermediate blade chambers, whereby the flow chambers of adjacent blade chambers (5) are at least essentially separated from each other. At least one guide rib (10) arranged between adjacent blades extends inwards into at least one cross-sectional region of the radial outer edging of the flow chamber. An independent claim is also included for a side channel machine.
