DEFINITION

Classification: 415/62

(under subclass 60) Apparatus comprising at least two distinct and different types of runners*, arrangements of blades* or directions of the working fluid* flow paths across the runner*.

(1) Note. The different arrangements of blades may be on a single runner; for example there may be a radial flow blade system and an axial flow blade stream, both systems fixed to and rotating on a single runner disc or hub.

(2) Note. Examples of different types of runners are: reaction, impulse, radial flow, axial flow, spiral or friction.

SEE OR SEARCH THIS CLASS, SUBCLASS:

81, for a runner* in which there is an interior flow path for working fluid* extending to the periphery of the runner* and discharging through a stream modifying orifice to cause rotation due to reaction of the discharge and also having a set of blades* on which the fluid discharging from the orifice impinges.

84, for a runner* having radial flow along plural concentric annular blade* series or rows and a peripheral blade* row of the axial flow type. 143, for a device having a plurality of separate and distinct runners*, in which the working fluid flows in or along one runner* in a path distinctly different type than it follows in at least one other runner*.
