Dynamic Gas Spring

Dynamic Damping Type
The gas spring is usually mounted on the tail gate or hood/bonnet, thus makes easy of lifting/lowering the coverlet. The gas spring is consisted with pressure tube(Cylinder), piston rod(Shaft), oil seal and other components.

Overview

The feature of dynamic gas spring
Unlike conventional hydraulic damping type by controlling piston orifice as oil passage, the dynamic gas spring give user very soft damping feeling and closing/open effort. It is available to set up the extension and compression speed of the piston rod for optimized usage condition by varying the groove parameter.

How to dynamic damping work
In this type of gas spring, piston does not have orifice in order for gas itself to run through the channel which is slotted on Speed the cylinder surface.

Feature

• Various range of application:
  From the furniture to automotive
• Merit of gas spring
  1. Sustaining of the constant elasticity change rate even in the high reaction force and long stroke.
  2. Compact design and appearance.
  3. Easy mounting and installing in any application at any position.
  4. Automatic operational dampering function without any additional adjustment device.
  5. Compression and extension speed adjustable.
  6. Reaction force will be adjustable at any time of usage.(in case of charge up)
• Various endfittings
