F16F 9/08

in a chamber with a flexible wall

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Springs, vibration-dampers, shock-absorbers, or similarly-constructed movement-dampers using a fluid or the equivalent as damping medium > using both gas and liquid > in a chamber with a flexible wall

CPC:

Springs, vibration-dampers, shock-absorbers, or similarly-constructed movement-dampers using a fluid or the equivalent as damping medium (F16F5/00 takes precedence; connection of valves to inflatable elastic bodies B60C29/00; ) > using both gas and liquid > in a chamber with a flexible wall

Of 6 combined children, 4 exist in both systems.

2 codes are CPC-only extensions.

IPC defines codes here since 1995.
