1. Operating characteristics of self-adjusting oscillating dampers
in a conventional oscillating damper, the damping strength (damping constant) does not change regardless of the load torque
used.
Therefore, the operating speed is slower when the load torque is small, and faster when the load torque is large.
However, since the self-adjusting FYN-A2 series is designed to self-adjustable the damping strength (damping constant)
according to the applied load, its motion-time fluctuates less than that of conventional dampers when the load changes.
The acceptable range of torque is 10 to 1 SN·m or 20 to 25N·m. Please select your damper by referring to the motion graph
below.

[Operating principles of the self-adjusting type)
As shown in the diagram to the left. by changing the shape of the valve (flat
spring). the amount of oil flow is altered, adjusting the damper's generated
torque. (PAT.P)

As the level of self-adjustment may vary
depending on the range of the working
angle of the actual work, please verify
under actual working conditions before
you select your damper.
