F16F9/5165 - CPC Classification

Classification description:

Springs, vibration-dampers, shock-absorbers, or similarly-constructed movement-dampers using a fluid or the equivalent as damping medium; Details; Special means providing automatic damping adjustment, resulting in the damping effects during contraction being different from the damping effects during extension, i.e. responsive to the direction of movement by use of spherical valve elements or like free-moving bodies
