Abstract
The present invention relates to a plugging device () comprising a housing (), a packer device (), a first supporting assembly () supporting a first side () of the packer device () in the expanded state and a second supporting assembly () supporting a second side () of the packer device () in the expanded state. The packer device () is provided circumferentially around the housing (); where the packer device () is configured to be provided in a retracted state and an expanded state, where the radial radius (R) of the packer body () in the expanded state is larger than the radial radius (R) of the packer body () in the retracted state. The packer device () comprises a packer body () and a supporting device () for supporting the packer body () in the expanded state. The first and second sides () of the packer device () and/or the supporting device () have the same circumference (C) in the retracted state and the expanded state, where the circumference (C) is larger than the circumference (C) of the housing ().
