DEFINITION
Classification: 277/589
Radially backed by resilient or elastomeric member:
(under subclass 500) Dynamic, circumferential, contact seal wherein the seal includes an elastic element to bias the sealing means in a direction perpendicular to an axis formed between the relatively movable parts.
SEE OR SEARCH THIS CLASS, SUBCLASS:
545, for a dynamic, circumferentially contacting, segmented ring for other than a piston having other than a nominal garter spring as a radial, biasing, spring element.
553+, for a dynamic, circumferential contacting, peripheral, radially sealing, flexible projection (e.g., a lip seal, etc.) including a bias means other than a nominal garter spring for other than a piston.
