Abstract

Et apparat og en fremgangsmåte for kompensering for under-vannstrykk på en hydraulikkrets, hvor nevnte apparat omfatter en kropp (42) som avgrenser et kammer (44) som har et stempel (50) skyvbart anordnet i seg, hvor kroppen (42) har en åpning (48) foran en utvendig side (54) av nevnte stempel (50), hyd-raulikkfluid (43) i kammeret (44) bak en innvendig side (56) av nevnte stempel (50), hvor nevnte hydraulikkfluid (43) er for kommunikasjon med en hydraulikkrets (45, 46, 47), kjennetegnet ved at nevnte stempel (50) har en stempelstang (60) forbundet med nevnte stempel (50) og skyvbart anordnet i et stempelstangkammer (72), og et trykkapparat (80) for å tilføre trykk i nevnte stempelstangkammer (72) til den andre stempelstang (60) og således holde et litt høyere trykk i hydraulikkretsen enn trykket i vannet rett rundt hydraulikkretsen. Hydraulikkretsen er fortrinnsvis en lukket hydraulikkrets. Trykkapparatet kan levere et positivt eller negativt trykk etter behov.
