DEFINITION

Classification: 277/579

Having floating ring or bushing (i.e., circumferentially contacting):

(under subclass 500) Dynamic, circumferential, contact seal wherein the seal is an annular or tubular seal 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 or perpendicularly to its main axis of motion.
