locking gas springs are used in fitness equipments, hospital beds, seat backs, and massage chairs and so on.
gas spring, gas lift, gas stay, gas strut, gas cylinder.
locking gas springs raise loads with an accurately tuned extension force and application-specific dampening while ensuring user-friendly movement sequences. In addition, locking gas springs can be blocked in any position, with springing or rigid blocking in the extension or compression direction depending on the design. Variable blocking is made possible by the valve integrated into the piston which separates both pressure chambers gastight. When the valve is closed, thereby interrupting the gas exchange between both pressure chambers, the lockable gas spring is blocked. The valve closes automatically when the valve tappet is released externally. The resilient blocking variant is ideal for the smooth dampening of e. G. Shocks, impacts or pulse-type peak loads.
