Class Information
Number: 415/199.5
Name: Rotary kinetic fluid motors or pumps > Working fluid passage or distributing means associated with runner (e.g., casing, etc.) > Plural rigidly related blade sets > Including an axial-flow blade set > Plural serial axial-flow blade sets with intermediate stationary flow diverter(s)
Description: Apparatus which includes at least another blade* set for contacting the working fluid* sequentially and wherein said fluid moves in a direction predominately parallel to the runner* axis as the fluid moves through each blade* set and which apparatus further includes immobile structure between the blade* sets for altering the directional movement of the fluid as it passes from a preceding blade* set to a succeeding blade* set.
