FIELD: underwater oceanographic research including floating of measurement equipment. SUBSTANCE: release includes chamber divided into upper and lower cylinders and charged with air at atmospheric pressure. Upper cylinder is fastened to instrument container, while lower cylinder is secured to armature. Joint between cylinders is provided with circular slot where circular rubber sealing gasket is laid. Upper and lower cylinders are interconnected by means of U-clamps evenly distributed over perimeter. Hold-down screws of U-clamps provided with springs are received by seats located on upper cylinder. Inlet passage is made in the form of valve gear secured on upper cylinder; it consists of gasket pressed by screws through fluoroplastic ring having hole for passage of outside medium. Bearing strut mounted opposite hole on side of inner chamber has taper head which is flatly cut at the top. Strut is pressed to mating taper seat in upper cylinder by means of lever revolving on axle; opposite end of this lever is supported by axle rigidly secured on upper cylinder through thrust strip. Strip is connected with armature of electromagnet located in hollow chamber. Controllable winding of electromagnet is connected with power supply source by means of signal wire; power supply source is located in instrument container. EFFECT: enhanced reliability. 1 dwgy
