Abstract
The present invention relates to an activating mechanism () for guiding and controlling a downhole tool () and/or subsea equipment employed in connection with recovery of hydrocarbons. The activating mechanism () comprises an annular sleeve () provided with non-through-going recesses () in the material of the annular sleeve (), where separate replaceable elements are provided in the recesses () to act as a pump (P), piston (S), reservoirs (R, R), movable slide (S) and pistons (), where these elements create a closed fluid circuit which on being subjected to a number of cyclical loads will open up a connection between the pistons (). A method for controlling the activating mechanism () is also presented.
