Abstract
A downhole tool for projecting a projectable element downhole includes a tool body having a radial bore, a projectable element forming a piston in the radial bore, the projectable element having first and second element parts. In the retracted position the projectable element and the second bore part define an annular cavity, a hollow base part having an open end and a closed end, the open end extending into the open first end of the projectable element forming a chamber. The open end of the hollow base part has at least one spring element arranged in the chamber and connected to the closed first end of the projectable element and to the closed end of the hollow base part for retraction of the projectable element, and a pump configured to pump fluid into the chamber via a fluid channel to project the projectable element.
