Class Information
Number: 415/173.7
Name: Rotary kinetic fluid motors or pumps > Bearing, seal, or liner between runner portion and static part > Between axial flow runner and vane or vane diaphragm structure
Description: 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*.
