224.~ Casing with nonradial flow runner (e.g., circumferential flow, etc.)


DEFINITION

Classification: 415/224

Casing with nonradial flow runner (e.g., circumferential flow etc.):

(under subclass 182.1) Device wherein the means comprises a casing* and wherein the working fluid* flow path through the runner* is in a direction other than predominantly inwardly

toward or outwardly from the runner's axis of rotation.

(1) Note. The flow path is often in a direction around the periphery of the runner (i.e., circumferential flow).
