ABSTRACT:
An actuator usable in a first fluid under a high pressure, e.g. on board a submarine operating at great depths to release or jettison ballast and wherein the first fluid is external to the submarine, comprises a plunger which is mobile by means of a spring and is held in place by a locking member. The plunger, its spring and the locking member are located within a frame which is filled with a second fluid, while a flexible skirt and two deformable sleeves enable the pressure of the second fluid to adapt constantly to that of the first fluid.
