Abstract

Anordning ved undervannsfarkost for utførelse av arbeid på havbunnen, fortrinnsvis ved store havdyp, slik som for eksempel ved havdyp større enn 200 meter. Undervanns- farkosten er en hydraulisk drevet farkost av i og for seg kjent gravemaskin-type utstyrt med arbeidsredskap, for eksempel graveskuffe, og aggregat for dannelse av hydraulisk drivtrykk til fremdrift av undervannsfarkosten og bevegelse av de armer og ledd som styrer arbeidsredskapet. På undervannsfarkosten er det anbragt en automatisk, trykkregulerende innretning for kompensering av det trykk som vanntrykket ved havbunnen utøver på undervannsfarkostens hydrauliske anlegg. Innretningen består av en stempel/sylinderkonstruksjon, der det omgivende vanntrykk virker mot stempelets bunnside og den hydrauliske oljestrømmen i anlegget er innrettet til å passere gjennom det av vanntrykket varierbare kammer mellom stempelets toppside og sylinderens topp og vegg, og det hydrauliske anleggets pumpe er elektrisk drevet ved krafttilførsel fra styreutstyr som befinner seg over havoverflaten.
