Abstract

Det beskrives en pakning til en brønn. Pakningen omfatter i det minste ett pakningselement, i det minste ett forankringselement, og en stamme koplet til det i det minste ene forankringselement. Pakningen er innrettet slik at når den er satt, er stammen fri til å forskyve seg med hensyn til paknings- og forankringselementene. I én utførelsesform er det i det minste ene forankringselement i ett med det i det minste ene pakningselement. I en alternativ utførelsesform er det i det minste ene forankringselement atskilt fra det i det minste ene pakningselement.
