The invention relates to a setting and retrieval device (1) for setting and/or retrieval of a plugging device in a well. The device comprises a first connection device (2) adapted to be connected to a first connection interface of the plugging device and a second connection device (3) adapted to be connected to a second connection interface of the plugging device. The setting and retrieval device further comprises a power supplying device comprising a fluid pump device (51) provided for pumping fluid between the first and second fluid chambers (41, 42) via a first fluid channel (11) and a second fluid channel (12). The setting and retrieval device further comprises a charging device (4) comprising a first fluid chamber (41) and a second fluid chamber (42), a displaceable charging piston (44) comprising a first end (44a) within the second fluid chamber (42) and a second end (44b) operable to energize an energy storing device (45), where the energy storing device (45) is charged with potential energy as the charging piston (44) moves in a first direction (A) when fluid is being pumped from the first chamber (41) to the second fluid chamber (42), and where a movement in a second, axial, direction (B) of the first connection device (2) relative to the second connection device (3) is achieved upon discharge of the energy stored in the energy storing device (45). The setting and retrieval device further comprises a volume adjusting device (7) comprising a first volume adjusting piston (71) is displaceable into the first fluid chamber (41). |
