DEFINITION
Classification: 277/305
Floating ring or bushing:
(under subclass 301) Close proximity seal wherein the seal is an annular or tubular seal forming a gap or clearance between the relatively movable parts and having relative movement between the relatively movable parts to oppose the flow of fluid.
(1) Note. A floater-type seal has relative motion between the relatively movable parts it seals between, whereas a seal that accommodates gyratory or oscillatory motion is capable of sealing relatively movable parts that move angularly, axially, or perpendicularly to its main axis of motion.
