Abstract

En nedihulls ventil (10) omfatter et legeme (12) som avgrenser et gjennomgående løp, og et ventilelement (22) som skal være plassert i legemet (12) og være bevegelig mellom en åpen stilling og en stengt stilling. Ventilen (10) har en første konfigurasjon, i hvilken ventilelementet (22) normalt er stengt og vil holde et trykkdifferensial i en første retning, og en andre konfigurasjon, i hvilken ventilelementet (22) er stengt og vil opprettholde et trykkdifferensial i den første retning og også i en motsatt andre retning, og en tredje konfigurasjon, i hvilken ventilelementet (22) er låst i den åpne stilling til det med forsett blir stengt.
