Abstract

Nedihulls verktøy (10) som omfatter et legeme med boring(12). Legemet (12) omfatter en ventilanordning (18) med strømningsporter (24) i legemets (12) vegg. Portene (24) kan åpnes og lukkes. I tillegg er det anordnet en regulerbar strømningsinnsnevring (30) i boringen(14), idet graden av innsnevring tenderer til å avta når en strømning gjennom innsnevringen (30) øker. Den variable strømningsinnsnevring (30) kan benyttes til å aktivere ventilanordningen(18).
