Abstract

En anordning for styring av strøm inne i f.eks. en produksjonsbrønn eller en innsprøytningsbrønn er vedlagt. Anordningen består av en bevegelig strømningspassasje og en stasjonær variabel strupning eller ventil som er sensitiv for strømningsparametere og som automatisk justerer seg for å tilveiebringe en forhåndsbestemt strømningsrate gjennom anordningen.
