(under subclass 208.1) Device wherein the vane* or other directing means lies in a plane normal to the runner's* axis of rotation, which plane passes through at least a portion of a working member blade*.
(1) Note. A device having a mere partition or wall with an orifice in which a runner* is positioned is not included in this subclass.
(2) Note. In axial flow devices, a "vane or other directing means" positioned about the periphery of a runner blade row is generally distinguished from a "casing" structure about the blade row in that a vane or other directing means (a) encloses the periphery of the blade row over less than half of the axial extent of the blade row and (b) does not act to support the runner.
