DEFINITION
Classification: 277/304
Formed by pressurized sealing fluid introduced to form barrier:
(under subclass 301) Close proximity seal wherein the joint or juncture has sealing fluid introduced into it at a pressure equal to or greater than the pressure of the sealed fluid to oppose the flow of the sealed fluid.

926, for a seal for other than a process of dynamic close proximity seal (e.g., contactless, fluent, etc.) created by pressurized sealing fluid introduced to form a barrier having means to create a fluid pressure equilibrium at a joint or juncture.
927, for a seal for other than a process of dynamic close proximity seal (e.g., contactless, fluent, etc.) created by pressurized sealing fluid introduced to form a barrier having means to create a fluid pressure different from the sealed fluid pressure.
