Abstract
A releasing device for disconnecting a buoyant body from an anchor a predetermined period after having been sunk into water. In order to accomplish a reliable device, which may be stored for very long periods of time, a piston is movable in a cylinder under the influence of a spring and a water pressure differential. The piston controls the disconnection of the buoyant body and the anchor, as the cylinder is connected to one part and the piston will release an element connected to the other part in a disconnecting position under the influence of the spring.
