Console (supporting) gas springs

A console (supporting) gas spring is a version of the standard gas spring in which the piston is equipped with a spring locking valve (Figure 11.). This valve prevents the gas flow between the two sides of the piston in the case of inward pushing. This locking valve opens only at a given pressure difference which can be set by the spring force supporting the valve. Consequently the inward pushing force is increased by the force obtained from the pressure difference. This is the additional supporting force. The force necessary for the inward push is thus: rated force + additional supporting force.

We produce console gas springs with 200N, 300N and 400N additional supporting force. The extension movement of the rod is unhindered, so the force of extension is unchanged.

The console gas spring is applied properly if it can lift the weight of a moving device (window, door, flap, cover, etc.) only with external help (by hand), but it can support it in any position along the stroke.

We produce console gas springs only with rod dia. 8mm and 10mm and damping 2. The additional supporting force is marked with a slash after the force of the gas spring (/2 = 200 N, /3 = 300 N, /4 = 400 N).
