DIFFERENCE BETWEEN ONE-WAY AND TWO-WAY DAMPER
Peir’s dampers include one-way damper (clockwise rotation or counterclockwise rotation) and two-way damper.
What is one-way damper?
One-way damper also has name of a uni-directional damper. It has a particular component, “one-way clutch” or “vane” in the rotary damper. When the damper is working, there is a damping in one direction and almost free movement in the opposite direction, or the damping force is relatively small.
One-way damper can be vane damper, gear damper, or disc damper.
As shown the figure below, the vane damper has two vanes attached onto the rotor. In different, one-way gear damper and one-way disc damper has a one-way clutch.
What is two-way damper?
Two-way damper means that the damper has damping in both directions. And the damping forces of clockwise and counterclockwise are almost equal. Two-way damper can be gear damper, barrel damper, or disc damper.
Application
One-way dampers are used in the heavy lid, or no damping force is required when returning. Such as toilet cover (PR-T098), washing machine lid (PR-T095), refrigerator home bar (PR-T093), curtain (PR-T058), etc.
Two-way dampers are used in automotive interiors and small home appliances, such as car armrest (PR-T022), cosmetic mirror (PR-T025), rice cooker (PR-T026), and kettle (PR-T009), etc.
