Definitions

the housing can be adapted or optimized.
the peripheral wall of the housing is removed the rear end of the wheel as seen in the direction of rotation of the impeller directly along the circumferential wall region running along the blade ring forming this spiral expansion angle increasingly radially from the impeller, being a continuous or abrupt transition is provided and the transition curvature can be optimized.
the blades of the blade ring also preferably take an angle to the radial direction that is most favorable Can be 26 - 29 °.
the housing 11 consists of a helically shaped Circumferential wall 18, with a curved part-circle Circumferential wall area 19 directly with a very small Gap of less than 1 mm along the blade ring 15 extends, in the exemplary embodiment over an angle of approx. 110 °. However, this angle can vary and between 60 ° and 150 °.
This peripheral edge area 19 is with a plurality of parallel groove-like depressions 20 provided, which are parallel to the axis of rotation of the impeller 10th extend and opposite the blade ring 15 of the impeller 10 effect a seal in the manner of a labyrinth seal.
the rotation of the impeller 10 produces small ones Vortex in the groove-like recesses 20, which is the target Sealing to increase fan performance and of the working pressure.
