DEFINITION

Classification: 277/391

Flexible sleeve, boot, or diaphragm:

(under subclass 390) Mounting seal or driving connection including a flexible wall member to accommodate relative axial movement between the sealing face member and one of the parts.

SEE OR SEARCH THIS CLASS, SUBCLASS:

389, for a relatively rotatable, radially extending, sealing face member (e.g., face, mechanical, etc.) including fluid pressure acting against a bellows or diaphragm to create an axial bias therefor.

504, for a dynamic, circumferential contact seal for other than a piston that accommodates gyratory or oscillatory motion by using a flexible connection having static contact between the seal and one of the relatively movable parts.

634+, for a static, contact flexible sleeve, boot, or diaphragm seal for other than an internal combustion engine, or a pipe, conduit, or cable.

384, Bearings, for more than nominal bearing structure or detail (e.g., liner, bearing race, cage, etc.) combined with a specific seal, 141, for a plain radial bearing having a relatively rotatable radially extending sealing face member (e.g., face, mechanical, etc.) including a diaphragm attached to it and a part axially movable therewith.
