Abstract

En avluftingsventil for et kabel-trykksetteverktøy er vist. Kammeret (40) i setteverktøyet avlurtes gjennom en avluftingsventilenhet som omfatter en bruddskive (42) som er festet over en åpning med en O-ringtetning (44). Det benyttes et gjennomboringsverktøy (64) som i forbindelse med bruddskivens (42) form danner et brudd i bruddskiven på en måte som ikke fører til at bruddåpningen gjentettes. Det er anordnet en alternativ avluftingsmekanisme basert på et tynt veggsegment (86) som kan gjennombores av et gjennomboringsverktøy (64) i tilfelle bruddskiven (42) av én eller annen grunn ikke skulle virke til å avlufte setteverktøyet.
