DEFINITION

Classification: 415/66

(under subclass 60) Apparatus in which the runners* are spaced in the path of the working fluid* and each succeeding runner* is acted upon by the fluid which has left the runner* next upstream thereof.

64, for plural runners* supported for relative motion or on separate shafts*, with working fluid* passing serially from one to the other, the flow being radial through concentric, radially spaced blade rows.

65, for plural runners* supported on separate shafts* or for relative motion, the blades* being interdigitated, oppositely extending, coaxially and axially spaced, the working fluid* following an axial path.
