Gas Spring-Lock Series: SUPERSEN-Gas Spring Lock Series Variable positioning, rigid or spring blocking Operating principle The version operates on the same principle as the Free Series. In addition, the gas spring features an integrated valve and can thus be blocked in any desired position. The piston is sealed at the pressure tube and separates two gas spaces. When the valve is closed, the gas spring is fixed which enables it to be blocked in any desired position. If the release plunger is operated, the valve is opened and the gas spring unit can be moved into any desired position.The extension rate and the damping can be varied accordingly by the choice of nozzle in the piston. Product Range The lock gas spring is available both in a resilient and also a rigid blocking version as follows: Standard range of products Fitted as standard with thread or eyelet end fittings Further connection variants available on request. Variants: Gas Spring Locking : Gas Spring Locking Type with resilient blocking in the extension or compression direction. If the piston is moved over the range of stroke in the gas, a resilient blocking effect is achieved as gas is compressible. Rigid Locking : Gas Spring Locking Type with rigid blocking in the extension or compression direction. If the piston is moved over the range of stroke in oil, a rigid blocking effect is achieved as oil is not compressible. In the case of the position independent rigid blocking variant, the gas and oil spaces are separated by a separating piston and rigid blocking is possible in the extension or compression direction on the design.
