DEFINITION

Classification: 415/208.2

Plural and arcuately or circularly arranged in radial plane around runner axis:

(under subclass 208.1) Device comprising at least two such vanes* or other directing means which are equidistantly spaced from the runner's* axis of rotation and are positioned in a (radial) plane perpendicular to the axis.

(1) Note. The guiding vanes or other directing means may intersect the runner's axis of rotation.
