This invention generally relates to firearms or more precisely—to devices providing underwater firing firearms from within the dry environment.
The device for underwater firing for a firearm comprises: a weapon with ammunition, a fire control tool and a controllable muzzle valve with a passage opening intended for passing of the projectile in the course of the underwater shot.
Moreover, the device comprises an outer housing having inside it at least a weapon and ammunition.
The fire control tool has at least one pyrotechnical charge intended to produce inside the housing before firing the excessive pressure exceeding the exterior water pressure.
Moreover, the fire control tool is connected with the muzzle valve that provides firing after opening of the muzzle valve in the result of increasing pressure of the pyrotechnical gas inside the housing and ceasing firing after closing of the muzzle valve.
The muzzle valve is installed in such a way that it can bypass the pyrotechnical gas from the housing into the water through its passage opening.
This invention increases the efficiency of firing under the water and reliability of the device for underwater firing from a firearm.
