DEFINITION

Classification: 415/182.1

WORKING FLUID PASSAGE OR DISTRIBUTING MEANS ASSOCIATED WITH RUNNER (E.G., CASING, ETC.):

(under the class definition) Device comprising means (e.g., casing*, etc.) to deliver, conduct, guide, direct, or distribute the working fluid* to, around, or from a runner*.

(1) Note. A device need not explicitly claim a runner to be in this and indented subclasses.

(2) Note. Patents in this and indented subclasses have been cross referenced to Class 416, Fluid Reaction Surfaces (i.e., Impellers), appropriate subclasses, where particular runner structure has been disclosed. See section IV of the Class

415 definitions for a discussion of class lines.

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.

108, for a device having a casing and a spaced housing with the space vented to working fluid.

126+, for a device having a casing part selectively movable relative to a fixed support. 134+, for a device having a casing with a thermal expansion joint.

144+, for a device having means to guide or conduct at least a portion of the working fluid along a path which bypasses the runner.

146+, for a device including working fluid force responsive vane or flow control means.

148+, for a device having adjustable means to affect or control the flow of working fluid.

138, Pipes and Tubular Conduits,

37+, for a fluid conduit having baffles or other means for changing the direction or rate of flow of fluid in the conduit.

239, Fluid Sprinkling, Spraying, and Diffusing, appropriate subclasses for means forming a free jet of fluid, the means not combined with runner structure.

416, Fluid Reaction Surfaces (i.e., Impellers), for particular runner structure.
