How Gas Springs Work

Gas springs provide direct support for safely lifting, positioning, lowering and counterbalancing weights.  They offer the versatility of a wide range of forces, simple mounting, compact size, speed controlled damping and cushioned end motion, combined with a flat force curve. 

The weight range supported can be a few kilos up to half a tonne, (from 50 to 5000 Newtons (2 springs). Gas springs incorporate proven engineering techniques with thousands of cycles of testing to ensure they meet the standards demanded by customers.

The most popular use is as a support on a horizontally hinged door. However, their versatility and ease of use has been applied to many other applications in industries ranging from transportation and office equipment to off-road vehicles, medical and leisure equipment.

A Camloc gas spring is a sealed energy source containing pressurised inert gas and a small amount of oil. Being self-contained units they require no power source or maintenance. With their tough ridgid construction, high structural integrity, they provide years of trouble-free operation.

Camloc gas springs work by forcing, under pressure, an inert gas (Nitrogen) into a cylinder. The internal pressure then greatly exceeds atmospheric pressure. This differential in pressure exists at any rod position and generates an outward force on the rod, making the gas spring extend.

This is due to: Force = Pressure x Area

When the rod is compressed into the cylinder, the internal pressure and the output force increase according to the volume displaced by the rod. On extension or compression, gas is transferred from one side of the piston to the other via a small orifice. This can be accurately metered to control either the rate of extension, compression or both.

At the end of the extension stroke, oil damping occurs due to a hydraulically cushioned zone. These features help protect hinges and mounts by applying constant force with a damped end of travel.

The flow rate of nitrogen and hydraulic oil is controlled while extending to maintain a controlled extension rate. The flow rate is increased in compression to ease movement.

A gas spring also contains a limited amount of oil that lubricates the seals, piston and piston rod.

When the rod is either compressed or extended, this movement of gas and oil within the cylinder from one side of the piston to the other, creates a damping effect, reducing sudden shocks on mountings, hinges and your application.
