Damping Engineering Functional Principle DICTATOR damping solutions offer four different lines of dampers: 1) EDH and ZDH final dampers Final dampers are used to slow down a movement before reaching the final position, e.g. with sliding doors in the positions OPEN and CLOSED. The relatively long stroke dimensions assure a sufficient safety zone. Final dampers are adjustable, to fit exactly the requirements of each door. 2) Oil dampers with fixings on both ends Oil dampers with fixings on both ends are connected firmly to the object that has to be damped (e.g. a flap). This way they...

Damping Engineering Functional Principle Functional Principle Basic Information Masses are moved almost everywhere in daily life and working units: doors and gates, flaps, transported goods or machinery parts. These involve high kinetic energy and high impact speed. If these forces are not controlled and slowed down, products and machinery can be damaged and people can get injured. DICTATOR dampers are based on the principle of transforming kinetic energy into thermal energy. The movement is transmitted to the damping cylinder - depending on the type of damper either via the piston rod or...

Damping Engineering Functional Principle Functional Principle - cont. The diameter of the throttling port in the piston is adjustable with the final dampers. There exist two different kinds of adjusting: - stepped adjustment - screw adjustment The stepped adjustment is more common. It has got its name by two toothed discs, which allow to adjust the opening of the throttling port only when being intertwined. The farther to the front the two discs are positioned the bigger is the flow opening for the oil, i.e. the less the damping. To adjust the opening of the throttling port the piston rod...

Damping Engineering Functional Principle Öldämpfer Titel Functional Principle of Oil Dampers with Fixings on Both Ends DICTATOR oil dampers with fixings on both ends are choosen, - when you need a damping as constant as possible during the whole travel. - if otherwise the risk of accident would be too high (e.g. with roof hatches). Oil dampers are installed in the same way as gas springs. But contrary to gas springs, which for example should assist in opening, they are intended to damp a movement (e.g. to prevent a hatch opening too fast downward). Detailed examples you will find in our...

Damping Engineering Functional Principle Functional Principle Radial Dampers DICTATOR radial dampers are designed to continuously control the speed of high masses on long distances. The movement is controled during the whole travel. Often they are used on sliding doors. To transfer the force to be controlled to the radial damper there exist different possibilities: by tensioned chain or rope, by revolving chain, rope or toothed belt, by rack or directly by a friction wheel on the radial damper. The radial dampers are furnished in two different base types: in a plastic casing or in an...

Damping Engineering Final Dampers DICTATOR Final Dampers DICTATOR final dampers are needed to slow down all kinds of rotative or linear movement. Their relatively long strokes offer sufficient saftey distances. The final dampers are available in both single (EDH) and bi-directional (ZDH) configurations. A large variety of dimensions is on stock. In addition we furnish customised dampers, same as with the oil dampers with fixings on both ends and the gas springs (see extra chapter) - even single pieces. The DICTATOR production programme is very comprehensive and thus offers solutions for a...

Damping Engineering Final Dampers Final Damper Variations Almost all dampers of the DICTATOR standard program can be produced as modified types. Generally just the relation between the diameter of piston rod and cylinder has to be observed. Apart from other dimensions a large range of other features is variable: material, finish, damping characteristics, end fittings, type of fixing, special damping fluids etc. On the following pages you will find the standard dampers of the different diameter series. Here all the above mentioned variables may be adapted to your requirements. Just ask our...

Damping Engineering Final Dampers Final Damper Variations, cont. Adjustment of the Damping Force The damping force of final dampers can be adjusted continuously. Depending on the application or the requirements this is either done with a screw in the front of the piston rod (screw adjustment = NR) or by pulling and turning the piston rod (stepped adjustment = ZR). A self-acting adjustment of the stepped adjustment is not possible, as this adjustment only works when you pull the piston rod sufficiently to engage two toothed discs on the piston. Only then you can adjust the damping force by...
