DEFINITION

Classification: 415/183

(under subclass 182.1) Apparatus comprising a plurality of members (e.g., vanes*, pipes, or nozzles) each of which has means to convey or direct a portion of the working fluid* directly onto the runner*.

(1) Note. The working fluid* streams may be directed to the same set of blades*, or to different sets of blades* on the same runner*.

(2) Note. A set of blades* or bucket comprises at least two physically interrelated blades* or buckets which cooperate with each other to form a single composite structure against which the working fluid* may act. The blades* or buckets of a set may be arranged relative to each other to form any one of a variety of shapes (e.g., circle, spiral) but usually comprises a single circular annulus.
