.~ Means to seal radial flow pump runner inlet from outlet
DEFINITION
Classification: 415/172.1
Means to seal radial flow pump runner inlet from outlet:
(under subclass 170.1) Device wherein the working fluid* path through the runner* is predominantly inwardly toward or outwardly from the runner's axis of rotation and wherein the runner adds energy to the working fluid (i.e., "pump"* runner). The means prevents or retards the flow of fluid between the runner's entrance and exit which flow does not pass through (i.e., is not acted upon by) the runner.
(1) Note. A circumferential or peripheral flow runner is not considered to be a radial flow runner for the purposes of this subclass.
