Introduced: January 1995

Title

Titles differ between systems:

IPC: the plastics spring forming at least a part of the wall of the fluid chamber of the damper

CPC: the plastics spring forming at least a part of the wall of the fluid chamber of the damper (F16F13/20 - F16F13/24 take precedence)

Full Title

Full titles differ between systems:

IPC:

Units comprising springs of the non-fluid type as well as vibration-dampers, shock-absorbers, or fluid springs > comprising both a plastics spring and a damper, e.g. a friction damper > the damper being a fluid damper, e.g. the plastics spring not forming a part of the wall of the fluid chamber of the damper > the plastics spring forming at least a part of the wall of the fluid chamber of the damper

CPC:

Units comprising springs of the non-fluid type as well as vibration-dampers, shock-absorbers, or fluid springs (F16F5/00, take precedence) > comprising both a plastics spring and a damper, e.g. a friction damper > the damper being a fluid damper, e.g. the plastics spring not forming a part of the wall of the fluid chamber of the damper (F16F13/26 takes precedence) > the plastics spring forming at least a part of the wall of the fluid chamber of the damper (F16F13/20 - F16F13/24 take precedence)

Of 5 combined children, 3 exist in both systems.

1 codes are CPC-only extensions, 1 exist only in IPC.

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1995.
