Abstract

Anordning ved støtdemper av den art som anvendes ved boring av hull i mineraler hvor demperen er innrettet til å dempe slag og vibrasjoner fra boreverktøyet, og hvor vibrasjons- demperen er forsynt med et væsketrykkpåvirket kompenseringa - areal (12') som er innrettet til å kompensere for de væske- trykkrefter som virker på rørendeflåten (111) og/eller andre væsketrykkpåvirkede flater, der en, i forhold til vibrasjons- demperen, aksiell kraftresultant oppstår.Device for shock absorbers of the kind used in drilling holes in minerals where the damper is adapted to dampen blows and vibrations from the drilling tool, and where the vibration damper is provided with a fluid pressure-influenced compensation - area (12 ') adapted to compensate for the fluid pressure forces acting on the raft (111) and / or other fluid pressure affected surfaces, where an axial force result is obtained in relation to the vibration damper.
