DEFINITION

Classification: 415/110

(under the class definition) Apparatus comprising a fluid

path between the normal working fluid* path and the interior part of an assembly which is positioned between two relatively moving apparatus parts (e.g., casing*, shaft*) the assembly service to (1) reduce or prevent unwanted working fluid* leakage between the parts, or (2) reduce the friction between the parts.

(1) Note. If the fluid path originates outside of the system or with a nonsystem fluid, it must discharge into the working fluid* path; if the working fluid* is the source for the seal, packing, lubricating or bearing assembly, it may then discharge outside of the system.

74, Machine Element or Mechanism, 5+, for runners supported in bearings for gyroscopic action and for a statement of the line see reference to Class 74 in section IV of the Main Class Definition of Class 415.

277, Seal for a Joint or Juncture, for a generic sealing means or process (e.g., seal between a runner* and another relatively movable part, seal between the two relatively moving members, does not recite enough details of the rotary kinetic device, etc.),

345+, for a seal between relatively movable parts (i.e., a dynamic seal).
