F16F SPRINGS; SHOCK-ABSORBERS; MEANS FOR DAMPING VIBRATION
Description
F16F covers mechanical devices and systems designed to store elastic energy, absorb impacts, and attenuate vibrations in machinery and structures. This subclass encompasses springs (helical, leaf, torsion, and other types), shock absorbers, dampers, and vibration isolation systems used across diverse applications from automotive suspension to industrial equipment. The classification includes both the devices themselves and functional mechanisms for energy dissipation, whether achieved through mechanical deformation, friction, or fluid resistance. Related applications in sealing, bearing design, and vibration control in specific machines are typically classified in their respective technical fields rather than F16F.
