Abstract
A wireline tool for sampling/jetting fluid in a well includes a pump with an opening, and a chamber for collecting/jetting fluid, the chamber having first and second ends. The chamber includes first and second pistons dividing the chamber into first, second and third chamber sections. The first and second pistons are attached to respective piston rods, and the rods are supported by respective supports. A first spring is provided between the first piston and its support and another spring is provided between the second piston and its support. When the pump operates, the pistons are forced in one direction, hence activating spring forces of the springs and allowing fluid to flow from one chamber section to another chamber section.
