A multifunctional downhole wireline tool for fluid sampling and fluid jetting in a well downhole, comprising: - a pump having a pump opening, and - a fluid chamber for collecting a sample of fluid or storage of fluid to be jetted, the fluid chamber having a first chamber end connected with the pump opening and a second chamber end having a chamber opening, wherein the fluid chamber has a chamber wall and comprises: - a first piston and a second piston dividing the fluid chamber into a first chamber section, a second chamber section and a third chamber section, the first piston being connected with a first end of a first piston rod, the second piston being connected with a first end of a second piston rod, - a first support configured to slidably support the first piston rod so that the first piston is movable in relation to the chamber wall, - a second support configured to slidably support the second piston rod so that the second piston is movable in relation to the chamber wall, and - a first spring (22, 22a) provided between the first piston and the first support and another first spring (22, 22b) provided between the second piston and the second support, so that when the pump provides a pressure difference over the pistons, the pistons are forced in one direction, hence activating a spring force of the first springs and allowing the fluid to flow from one chamber section to another chamber section, wherein the chamber wall comprises at least one groove arranged along a longitudinal extension of the fluid chamber, the groove being arranged opposite the piston in an open position of the piston where fluid is allowed to flow from one chamber section to another. - a pump having a pump opening, and - a fluid chamber for collecting a sample of fluid or storage of fluid to be jetted, the fluid chamber having a first chamber end connected with the pump opening and a second chamber end having a chamber opening, wherein the fluid chamber has a chamber wall and comprises: - a first piston and a second piston dividing the fluid chamber into a first chamber section, a second chamber section and a third chamber section, the first piston being connected with a first end of a first piston rod, the second piston being connected with a first end of a second piston rod, - a first support configured to slidably support the first piston rod so that the first piston is movable in relation to the chamber wall, - a second support configured to slidably support the second piston rod so that the second piston is movable in relation to the chamber wall, and - a first spring (22, 22a) provided between the first piston and the first support and another first spring (22, 22b) provided between the second piston and the second support, so that when the pump provides a pressure difference over the pistons, the pistons are forced in one direction, hence activating a spring force of the first springs and allowing the fluid to flow from one chamber section to another chamber section, - a first piston and a second piston dividing the fluid chamber into a first chamber section, a second chamber section and a third chamber section, the first piston being connected with a first end of a first piston rod, the second piston being connected with a first end of a second piston rod, - a first support configured to slidably support the first piston rod so that the first piston is movable in relation to the chamber wall, - a second support configured to slidably support the second piston rod so that the second piston is movable in relation to the chamber wall, and - a first spring (22, 22a) provided between the first piston and the first support and another first spring (22, 22b) provided between the second piston and the second support, so that when the pump provides a pressure difference over the pistons, the pistons are forced in one direction, hence activating a spring force of the first springs and allowing the fluid to flow from one chamber section to another chamber section,
