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.
