DEFINITION

Classification: 415/208.1

Vane or deflector:

(under subclass 182.1) Device wherein the means to deliver, conduct, guide, direct, or distribute the working fluid* to,

around, or from the runner* comprises a static (nonrotating) partition member vane* or other working fluid directing means in the working fluid flow path.

(1) Note. A device comprising mere working fluid conducting passage walls is not included in this subclass.

(2) Note. A device comprising plural vanes or other working fluid directing means immediately upstream of a runner is not included in this subclass. See subclasses 183+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

2.1+, for a device with means for controlling casing* or flow guiding means in response to natural fluid current force or direction which means may include a vane or deflector.

8, for a device having a driven, fluid immersed runner with a vane in an unconfined fluid stream.

12, for a device with a bimetallic vane or vane adjustment means. 53.2, for a device having a cross flow runner blade* set and a vane or flow guide inside the blade set.

55.2+, for a turbine regenerative pump* having means to deflect working fluid in a regenerative passage.

142, for a device comprising a shaft* bearing combined with or retained by a vane in a surrounding working fluid space.

146+, for a device comprising working fluid force responsive vane control.

148+, for a device comprising selectively adjustable vane or other working fluid control means.

173.7, for a device comprising bearing, sealing, or liner structure between a vane or vane diaphragm structure and an axial flow runner.

183+, for a device comprising plural vanes or deflectors immediately upstream of a runner.

199.1+, for a device comprising serial, rigidly related, radial flow blade* sets and an intermediate stationary flow diverter.

199.5, for a device comprising serial, rigidly related, axial flow blade* sets and an intermediate stationary flow diverter.

218.1, for a device with a working fluid directing conical runner hub (integral with runner) having its small diameter facing upstream.
