(under subclass 411) Gap or clearance wherein the gap or clearance includes an annulus or tubular seal having relative movement at the joint or juncture and having relative movement free of relatively movable, sealing contact against the relatively movable parts.
(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 or perpendicularly to its main axis of motion.
