Blokerbare typer | Types of lockable gas springs
B Type
K Type Hvis en blokeret gasfjeder udsættes for en belastning, vil blokeringen være stabil, indtil den mekaniske belastnings- grænse for gasfjederen nås. Hvis den udsættes for belastning i sammenpres- ningsretningen, vil fjederen være stabil, indtil presset på den flydende stempel- stang overskrides (blokeringskraft). Hvis dette sker, skubbes stempelstan- gen en smule ind, hvilket kan se ud som en sikkerhedsfunktion mod overbelast- ning.
P Type
KX Type Her kombineres fordelene ved blokerbare gasfjedre af Type K og P i samme fjeder. Låsekraften i begge retninger er stabile, indtil fjederens mekaniske styrke overskrides. Derfor fås modeller- ne KX også uden tryk, men med stabil låsekarakteristik. Typiske funktioner: Mekanismer til kompensation, sædekompensatorer, sygesen- ge, Trendelenburg-justering. Here, the advantages of the K- and P-type of lockable gas springs are combined in one spring. The locking force in both directions is rigid up to the mechanical strength of the spring. Therefore, KX-models are also available without pressure but have rigid locking characteristics. Typical applications: Compensator mechanisms, seat compensators, medical beds, Trendelenburg adjustment.
Med denne type blokerbare gasfjedre, er blokeringen fleksibel i begge retninger. Afhængig af den pågældende belastning, kan en forskydning forekomme ved blokering. Selvom gasfjederen blokerer, vil der være en behagelig dæmpning.
Funktionen minder om Type K, men olie- og gaskammeret er på den anden side. Det betyder, at fjederen er stabil, indtil fjederens mekaniske styrke i sammenpresningsretningen. I forlænget retning er blokeringen stabil, indtil kraften af presset på den flydende stempelstang overskrides (låsekraft). Hvis dette sker, skubbes stempelstan- gen en smule ind, hvilket kan se ud som en sikkerhedsfunktion mod overbelast- ning. Typiske funktioner: Justering af f.eks. senge (især ved udsættelse for ekstra tung vægt). The function is similar to that of a K-type but the oil and gas chamber is on the opposite side. This means that the spring is rigid up to the mechanical strength of the spring in compressed direction. In extended direction, the locking is rigid until the force of the pressure on the floating piston is exceeded (locking force). If this occurs, the piston rod inserts a little bit which may look like a overload safety device. Typical applications: Adjustments for applications such as beds (especially if high additional loads apply).
Typiske funktioner: Justering af sædehøjde.
In this basic type of lockable gas springs, the locking remains flexible in both directions. Depending on the force applied, a displacement will take place when locked. Although the gas spring is locked, there will be a comfortable damping.
Typiske funktioner: Justering af ryglæn.
If a force is applied on the locked gas spring, the locking remains rigid up to the mechanical strength of the gas spring. If a force is applied in com- pressed direction, the spring remains rigid until the force of the pressure on the floating piston is exceeded (locking force). If this occurs, the piston rod inserts a little bit which may look like a overload safety device.
Typical applications: Seat height adjustment.
