54.1.~ To opposite face of blade


DEFINITION

Classification: 415/54.1

To opposite face of blade:

(under subclass 52.1) Device wherein the working fluid* directed back to the blade* or blade row is directed to a surface (i.e., face) of the blade or blade row on the other (i.e., back) side of a surface previously contacted by the working fluid.

(1) Note. In most instances, the arrangement under this definition is for the purpose of slowing down the runner since the redirected fluid acts on the blade in a direction opposite to that in which the working fluid originally acts.
