FIELD: harpoon hydropneumatic guns for underwater shooting. SUBSTANCE: for shooting air is injected to the working cylinder cavity through a check valve. At installation of the harpoon in the barrel in water, water is fed through a hole in the barrel to the cavity behind the piston displacing the piston. When it is necessary to increase the ejection force, water is pumped up into the cavity behind the piston by means of the hydraulic pump. For adjustment of pressure use is made of a screw located in the outlet, with the aid of this screw it is possible to decrease the ejection force or discharge the gun at all. EFFECT: improved design. 3 cl, 2 dwg
