Device (A) for controlling and/or operating a tool, a device or underwater equipment employed in connection with exploration and recovery of hydrocarbons offshore or onshore. The device (A) comprises a hollow sleeve (S) with a number of recesses (U, Ut1, Ut2) and a closed volume (V), in which recesses (U, Ut1, Ut2) a movement mechanism (M), a stopper element (21) and a block release element (8) are mounted, where, when influenced by cyclic loading, the movement mechanism (M) will be moved relative to the stopper element (21) and the block release element (8) into a position where the block release element (8) via a release pin (7) will open up a connection between the closed volume (V) and a number of relief recesses (AU), whereby at least one push rod (26) is activated for operating in the device's (A) longitudinal direction, where the implementation of the release pin (7) is employed for controlling or operating the tool or the underwater equipment. |
