Abstract
Device for controlling and/or operating underwater equipment employed in connection with recovery of hydrocarbons. The device has a hollow sleeve with a number of recesses and a closed volume, in which recesses a movement mechanism, a stopper element and a block release element are mounted. Under cyclic loading, the movement mechanism will be moved relative to the stopper element and the block release element into a position where the block release element via a release pin will open up a connection between the closed volume and a number of relief recesses. At least one push rod is activated for operating in the device's longitudinal direction.
