Abstract
Device for controlling the submersion depth of an element moving through a body of water comprising a pivotable wing having an upper and a lower wall articulated to each other at one end and interconnected at the other end through a deformable incurved wall, the wing housing spacing elements, between the upper and the lower wall, which are compressed or expanded in response to the hydrostatic pressure variation, resulting from a depth variation of the element, thereby producing a space variation between the two walls, and a system for converting said space variation to a rotation of the wing with respect to the submerged element, in a direction at which the movement of the element tends to an opposite variation of the hydrostatic pressure.
