Abstract

Utførelser av den foreliggende oppfinnelse tilveiebringer en mer driftssikker regulerbar strupeventil (100) for strømningsregulering. I én utførelse tilveiebringes en regulerbar strupeventil (100) til bruk i et borehull. Ventilen (100) innbefatter et rørformet hus (4) med en gjennomgående aksialboring og en port gjennom en vegg i huset (4). Ventilen (100) innbefatter videre en rørformet muffe (10) som har en gjennomgående aksialboring og et første og et andre hull (300) gjennom en vegg i muffen (10), og som er anordnet inne i huset (4). Det første hull (300) er større enn det andre hull. (300), og muffen (10) beveges mellom tre stillinger; en første stilling hvor det første hull (300) er i flukt med porten, en andre stilling hvor det andre hull (300) er i flukt med porten, og en tredje stilling hvor muffeveggen er i flukt med porten.
