BLOC-O-LIFT® gas springs raise loads with an accurately tuned extension force and application-specific dampening while ensuring user-friendly movement sequences. In addition, BLOC-O-LIFT® 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 BLOC-O-LIFT® 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 (e.g. in seats and office swivel chairs).
