DEFINITION

Classification: 277/503

Accommodates gyratory or oscillatory motion:

(under subclass 500) Dynamic, circumferential contact seal wherein the seal permits angular or lateral deflection, circular displacement, eccentric movement, or vibration of one or more of the relatively movable parts.

(1) Note. 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 whereas a floater type seal has relative motion between the relatively movable parts it seals.
