DEFINITION

Classification: 415/56.4

Reentry through working fluid discharge passage for runner:

(under subclass 56.1) Device comprising a conduit through which the (reentry) working fluid* portion is directed to the runner* blade* or blade row, which conduit also serves to guide the working fluid away from the runner blade or blade row.
