.~ Between axial flow runner and vane or vane diaphragm structure
DEFINITION
Classification: 415/173.7
Between axial flow runner and vane or vane diaphragm structure:
(under subclass 170.1) Device wherein the working fluid* path to, through, and from the runner* is predominantly parallel to the runner's rotational axis (i.e., axial flow). The means is positioned between the (axial flow) runner and a partition member vane* or a structure which secures one or more such vanes in position relative to a casing*.
(1) Note. A seal means which retards or prevents flow between a multiblade row axial flow runner and a vane or vane diaphragm structure which seal means is located between blade rows of the runner is included in this subclass.
(2) Note. The structure which secures one or more vanes in position relative to a casing usually secures the vanes arcuately about and in a radial plane perpendicular to the rotational axis.

173.1+, for a device having a seal between a runner* blade* edge and a static part, which static part may comprise a vane* or vane diaphragm portion.
