Claims (4)
1. Et beskyttelseshylsearrangement for å beskytte deler av et stigerør mot avleiringer, sand, kjemikalier, slag eller andre skadelige elementer som kan ha negativ innvirkning på delen som skal beskyttes, omfattende en beskyttelseshylse (3) anordnet inne i et stigerør (1), hvor nevnte hylse (3) samspiller med det indre av nevnte stigerør (1) for å danne et første hydraulisk trykkammer (5) og et andre hydraulisk trykkammer (8), og at et høyere trykk i det første hydrauliske trykkammeret (5) enn i det andre hydrauliske trykkammeret (8) vil forflytte beskyttelseshylsen (3) i en første lengderetning inne i stigerøret og vice versa.
2. Beskyttelseshylsearrangementet ifølge krav 1, hvor beskyttelseshylsen (3) når den er i en første lengdeveis posisjon strekker seg gjennom boringen til en skjærtetning (2)
3. Beskyttelseshylsearrangementet ifølge krav 1 eller 2, hvor det omfatter en første tetning (6) montert på innsiden av stigerørsdelen, for å forsegle én ende av det første hydrauliske trykkammeret (5), en andre tetning (9) montert på innsiden av stigerørsdelen, for å forsegle én ende av det andre hydrauliske trykkammeret (8) og en hylsetetning (7), montert på beskyttelseshylsen (3), og anordnet mellom nevnte første og andre tetninger (6, 9), og som derved definerer et skille mellom det første og andre hydrauliske trykkammeret (5, 8).
4. Beskyttelseshylsearrangementet ifølge krav 3, hvor en flensforbindelse (13a, 13b) mellom stigerørsseksjoner er anordnet mellom den første og den andre tetningen (6, 9).
