Abstract
En anordning for bruk i en brønnboring inkluderer generelt en strømningsrørkanal og en struktur som avgrenser et snirklet fluidløp nær strømningsrør-kanalen, hvor det snirklete fluidløp mottar en strøm av fluid. Det snirklete fluidløp er avgrenset av i det minste første og andre organer av strukturen, og de første og andre organer er bevegelige i forhold til hverandre for å justere et tverrsnittsstrømningsareal av det snirklete fluidløp.
