Abstract

En oppblåsbar pakning (10) innbefatter en glidbar hylse (86) som åpner og lukker en åpning (94) for derved å styre trykksettingen av et oppblåsbart pakningselement (120) ved hjelp av et sement-fluidum. Hylsen (86) beveges aksialt ved hjelp av et verktøy (20) som henger i brannen i en arbeidsstreng (WS). I pakningshuset er det utformet en ringformet passasje (76) fra innløpsåpningen (94) til pakningselementet (120), for derved å muliggjøre en pålitetlig oppblåsing med sement-fluidum. Hylsen (86) gir metall-metall-tetning mot et indre hylselegeme (76) i pakningshuset for oppnåelse av en pålitelig avtetning av det oppblåsbare kammer relativt brønnfluider når hylsen (86) er stengt.
