DEFINITION

Classification: 277/634

Flexible sleeve, boot, or diaphragm:

(under subclass 628) Contact seal for other than wherein the seal has a flexible wall member to accommodate relatively movable parts allowing static contact sealing against the parts.

SEE OR SEARCH THIS CLASS, SUBCLASS:

315, for a process of static sealing employing a flexible sleeve, boot, or diaphragm.

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.

391+, for a relatively rotatable, radially extending, sealing face member (e.g., face, mechanical, etc.) including a flexible sleeve, boot, or diaphragm to provide a secondary seal or driving connection 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.

251, Valves and Valve Actuation, for means to close or

restrict a flow of fluid through a passage by a definite predetermined motion of the means combined with a seal,

335.1+, for a flexible wall seal between an actuator and valve.

403, Joints and Connections, for a joint or connection structure that goes beyond providing an environment for a seal;

50+, for a flexible diaphragm or bellows secured to each part.

464, Rotary Shafts, Gudgeons, Housings, and Flexible Couplings for Rotary Shafts,

173+, for a flexible boot for a joint to transmit rotary torque.
