发明名称 Activating mechanism
摘要 The present invention relates to an activating mechanism (200) for guiding and controlling a downhole tool (100) and/or subsea equipment employed in connection with recovery of hydrocarbons. The activating mechanism (200) comprises an annular sleeve (21) provided with non-through-going recesses (22, 24) in the material of the annular sleeve (21), where separate replaceable elements are provided in the recesses (22, 24) to act as a pump (P), piston (S1), reservoirs (R1, R2), movable slide (S2) and pistons (25a, 25b), 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 (25a, 25b). A method for controlling the activating mechanism (200) is also presented.
