Gas Struts are often referred to as Gas Springs. In this article we look at the various types of Gas Strut available and what makes them different and thus suitable for different applications.
Compression Gas Struts
Compression Gas Struts provide an outwards pushing force that can be utilised to assist the movement of an object i.e helping in the movement of a door or hatch The basic configuration includes a rod with piston attached that moves up and down inside a gas/oil chamber. As the rod moves into the body of the gas strut it reduces the volume that the gas/oil can occupy and thus the pressure inside the sealed tube increases and an outwards force is exerted on the rod.
Compression gas struts have the rod out and the load from the application forces the rod in. Typically a gas strut is mounted so they are rod down in the position in which they spend the most time. This allows the oil contained within the gas strut to lubricate the rod seals.
The same basic concepts as a Compression Gas Strut but this product has a side release valve that is operated with an Allen key. You can release the pressure whilst the Gas Spring is on the application, saving you time.
With a locking Gas Strut, they provide a pushing force like a compression gas spring but can be locked off in any position by the simple action of a lever or remote button.
Friction Lock Compression Gas Struts
These use a large easy to grip nut to quickly lock off the Gas Strut in any position you wish. The spring operates just like a standard compression gas strut when unlocked.
Lock Open Compression Gas Struts consist of a standard compression gas strut with a special protection sleeve which is on a pivot mounting. This sleeve automatically falls into place when the gas strut has reached its full extension, effectively locking your application in the open position.
If your application is in a dusty/dirty environment, likely to suffer impacts to the rod or of a particularly long stroke length then it is advisable to use Protected Compression Gas Strut.
