Locking Gas Springs

Locking Gas Springs is a gas spring with a mechanism that enables the piston rod to be locked at any desired position in extension or compression. It offers high rigidity and resistance against shocks and jerks when the shaft blocked in a particular position.



There are three types of gas springs, depending on the gas and oil chamber configuration:

Spring Blocking:

In this type of springs, one of the compartments is for oil and gas. Due to gas compressibility, the spring exhibits a slight deflection under load and in blocked condition. It generates a suspension type effect, which is useful for applications, such as office chair push back. The deflection depends on the initial force and load applied.



Rigid Blocking in Extension:

In this type of springs, oil and gas compartments are separated by a piston. The oil chamber is located in between the main piston and seal assembly. The gas spring is rigid in extension due to low compression ability of oil. The deflection in extension is practically nil under working load. Some typical applications, like passenger seats, and hospital beds, require these springs.
