Lockable gas spring working principle description
A lockable gas spring works similarly to a standard gas spring but includes an internal locking mechanism that allows the piston rod to be locked in any position along its stroke. Here's a breakdown of the working principle:
Working Principle
1. Neutral Position (Locked)
When no external force is applied (e.g. the button is not pressed), the internal valve is closed.
This blocks the flow of gas or oil from one side of the piston to the other.
As a result, the piston rod cannot move, effectively locking the gas spring in place.
The lock can be rigid (hard locking) or flexible (soft locking), depending on whether it resists all force or allows slight cushioning.
2. Unlocked Position (Adjustable)
When the release mechanism is activated (e.g. by pressing a lever), the internal valve opens.
Gas or oil can now flow freely between chambers.
This allows the piston rod to move, making the gas spring adjustable in length or angle.
Once the desired position is reached and the release is stopped, the valve closes again, locking the position.
