Locking gas spring with elastic locking

The elastically lockable gas springs are then to be recommended if a spring-back of the lock is desired. Pulsed peak loads can be damped or even avoided this way.

  • Model EL1 and EL2

    These two models differ only in the diameter of the pressure tube. Since the piston separates two gas chambers when the valve is closed, the piston rod also springs in the locked state due to exterior loads. Pulsed peak loads are damped or even avoided. This makes applications possible that require convenient locking.
