Abstract

Et direkte proporsjonalt styringssystem for fjernstyring av aktiveringen av et brønnverktøy (16) er tilveiebrakt. Et brøimstyringssystem (10) inkluderer en aktivator (20) for et nedihulls brønnverktøy (16), hvilken aktivator (20) inkluderer et aktivatorelement (32) som forflyttes for å operere brønnverktøyet (16). Et styringssystemelement (30) er anordnet på et ^emt sted. En forflytning av styringssystemelementet (30) foregår proporsjonal med en forflytning av aktivatorelementet (32).
