Description

F16J covers pistons, cylinders, pressure vessels, and sealing systems that function as fundamental mechanical components across diverse industrial applications. This subclass includes piston designs and piston rings, cylinder construction and linings, general-purpose pressure vessels, and various sealing mechanisms (gaskets, packings, dynamic and static seals). The classification addresses the mechanical engineering aspects of these components, excluding their application in specific machinery types, which are classified in their respective technical fields.
