Abstract

A setting and retrieval device includes a first connection device connected to a first connection interface of a plugging device and a second connection device connected to a second connection interface of the plugging device. The device includes a charging device having first and second fluid chambers, a displaceable charging piston, a power supplying device included a fluid pump device for pumping fluid between the first and second fluid chambers via first and second fluid channels, and a volume adjusting device including a volume adjusting piston displaceable into the first fluid chamber. The energy storing device is charged with potential energy by the charging piston moving in a first direction by pumping fluid from the first to the second fluid chamber and the energy stored in the energy storing device is discharged by movement in a second, axial, direction between the first and second connection devices.
