摘要: A downhole stroking tool comprising a housing (2), a first chamber (3), a first tool part comprising a pump unit (5) providing pressurised fluid to the chamber, a shaft (6) penetrating the chamber (3), and a first piston (7) dividing the first chamber into a first chamber section (8, 8a) and a second chamber section (9, 9b). The piston (7) is connected to or forming part of the housing forming part of a second tool part (10) and is slidable in relation to the shaft (6) so that the housing (10) moves in relation to the shaft (6), the shaft being stationary in relation to the pump unit during pressurisation of the first or the second chamber section, generating a pressure on the piston, wherein the shaft is fixedly connected with the first tool part, and wherein the housing is slidable in relation to the first tool part and overlaps the first tool part.
