F16F9/04 - CPC Classification

Classification description:

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

Sub-classes:

F16F9/0409 » {characterised by the wall structure} 70
F16F9/0418 » {having a particular shape, e.g. annular, spherical, tube-like } 35
F16F9/0436 » {characterised by being contained in a generally closed space} 11
F16F9/0445 » {characterised by intermediate rings or other not embedded reinforcing elements } 20
F16F9/0454 » {characterised by the assembling method or by the mounting arrangement, e.g. mounting of the membrane } 121
F16F9/0472 » {characterised by comprising a damping device } 70
F16F9/049 » {multi-chamber units } 62
F16F9/05 » the flexible wall being of the rolling diaphragm type 165
