Abstract

Det er frembragt et defleksjonsapparat eller avbøyningsanordning (10). I en beskrevet utførelse omfatter anordningen en dreiemomentbestandig gjenvinnbar ledekile (24) som på tettende måte er festet til en pakning (26). Ledekilen kan adskilles fra pakningen ved at det påtrykkes en aksial kraft på et første hus (32) og derved frigjøres en hylse (48) som på tettende måte er anordnet mellom det første huset og et andre hus (34) for forskyvning i forhold til det andre huset. Dest første huset (32) og hylsen (48) kan så fjernes fra innsiden av det andre huset (34) og etterlater en tetningsboring med relativt stor diameter over pakningen (26).
