A Spring locking gas spring is a basic type of lockable gas spring, where the locking is achieved in gas. It is typically applied for use in seat height adjustment. The piston travels completely in compressible nitrogen gas. When the valve is closed, this type can be positioned anywhere along the stroke but the locking is elastic. Depending on the amount of force applied, a displacement will take place when locked, allowing for comfortable damping. The construction corresponds mainly to that of a standard gas spring, only instead of a nozzle works a piston in the gas chamber. The gas which is on both piston sides can be compressed with the corresponding load. The locking force is, depending on the position of the piston, more or less low. The smaller the gas chamber between piston and the respective end part, the higher the figure.

Overview
A gas spring is a type of spring that, unlike a typical metal spring, uses a compressed gas, contained in a cylinder and variably compressed by a piston, to exert a force. Gas springs are used frequently in automobile construction, where they are commonly used to support the weight of vehicle doors while they are open. They are also used in furniture, medical, and aerospace applications.
Contrary to a standard gas spring, a lockable gas spring can be adjusted continuously in every required position. Classic fields of application are e.g. height adjustments of tables, adjustments of back rests of beds or armchairs.
