DICTATOR high-performance gas springs lift your loads - always smoothly and effortlessly, without jolt. The variety of applications is as numerous as our models. For that reason DICTATOR has no fix table of types and only some frequently ordered gas springs are available from stock. We manufacture your gas spring for your particular application - also single units or small quantities. As a counterweight, or to assist movement DICTATOR high-performance gas springs are ideally suited to a wide variety of applications. They give controlled movement smoothly and effortlessly. In gas springs a...

Basic Principle In this section you will find a detailed explanation concerning the functioning of the different types of gas springs. All gas springs work on the same basic principle: Gas springs are filled with nitrogen gas to a suitable pressure. This pressure is equal on both sides of the piston. The piston rod always extends because the surface area of the piston with the piston rod attached is smaller than the surface area of the other side of the piston with no piston rod attached. The resultant force F in Newtons [N] can be calculated by multiplying the gas pressure P [bar] by the...

Push Type Gas Springs In this section you will find a detailed explanation concerning the functioning of the different types of gas springs. All gas springs work on the same basic principle (see previous page): the gas pressure acting on the inside surface area of the piston rod forces the piston rod outwards of the cylinder. The resultant force F in Newton [N] can be calculated by multiplying the internal pressure P [bar] by the surface area A of the piston rod [mm2]: F = P x A Push Type Gas Springs Piston port As mentioned on the previous page, gas springs contain highly pressurised...

Gas Springs with Floating Piston and Pull Type Gas Springs Gas springs with floating piston have a second sealed piston additionally to the main piston which is attached to the piston rod. This floating piston separates the pressurised gas section from the oil or empty volume section. It moves and transfers the pressure of the gas to the oil in the front part of the cylinder. Gas Springs with Floating Piston Floating piston Inside gas springs with floating piston the section containing the normal piston is filled with oil. The small port in the piston causes the piston rod to move slowly....

Locking Gas Springs In locking gas springs the port in the piston is closed by a valve which is opened by a release pin located inside the piston rod. The piston rod can only move if the locking mechanism is disengaged. Cushioned locking gas springs compress slightly when a load is applied without disengaging the locking feature, as the gas compresses in both directions. Locking gas springs are used to lock levers and flaps in various positions. They should balance out the weight of the flap when released. Cushioned Locking Gas Springs Locking valve: closed - open The locking valve in the...

Double Cylinder Gas Springs DICTATOR double cylinder gas springs consist of two cylinders connected by an adjustable valve. This enables you to reduce the extending speed and control it exactly. The pressurised gas is sealed from the oil compartment by a floating piston. A valve at the front end of the gas cylinder enables you to release gas for reduced gas spring force. Double cylinder gas springs are used in applications where a slow and adjustable extending speed is required. They can be used to automatically open folding doors in fire station buildings, for example. Double Cylinder Gas...

Additional Options This section provides information on additional options which enable you to employ gas springs in certain applications, or simply make them much easier to use. The additional options suitable for each gas spring can be found in the data pages corresponding to each type of gas spring (starting on page 06.017.00). Please pay attention to details concerning the different lengths of gas springs as some additional options increase the minimum length of the cylinder. Temperature, Corrosion Gas springs are filled with nitrogen gas and hydraulic oil at approx. 20 °C. Internal...

Oil Chamber and Valve These accessories enable DICTATOR gas springs to be used in conditions where normal gas springs would have little durability, or could only be adjusted to different forces at high cost. Oil chambers (order code 4) and valves (order code 5) are available for most DICTATOR gas spring models. You will find further information in the detailed description of each type of gas spring starting on page 06.017.00. Virtually all DICTATOR gas springs are available with an additional oil chamber. This prevents the seal on the piston rod from drying out and failing. The oil also...

Protective Tube This accessory enables DICTATOR gas springs to be used even in particularly dirty or rough conditions e.g. on road sweepers and sand blast cabins. If necessary an additional protective tube (double protective tube) can be fitted over the first protective tube. ø Protective tube ø Piston rod Protective tubes (order code 6 or 9 for stainless steel) and double protective tubes (order code 6-6 or 9-9 for stainless steel) are available for most DICTATOR gas springs. Details can be found on pages 06.017.00 - 06.058.00 further back in this catalogue. We recommend you order a...
