DEFINITION

Classification: 277/423

Impeller (e.g., slinger, etc.):

(under subclass 409) Close proximity wherein the close proximity seal provides a rotary motion transmitting means to direct, deflect, or distribute the sealed or sealing fluid into opposing the flow of fluid.

400, for a relatively rotatable, radially extending, sealing face member (e.g., face, mechanical, etc.) providing a hydrodynamic feature.

SEE OR SEARCH CLASS

384, Bearings, for more than nominal bearing structure or detail (e.g., liner, bearing race, cage, etc.) combined with a specific seal,

132+, for a plain, radial bearing where the seal is a barrier of liquid or gas, or subclass 478 for a radial, antifriction bearing where centrifugal force loads the seal or a liquid or gas forms a sealing barrier.
