ARRANGEMENT OF REGULATION OF POSITIVE FLOATATION OF UNDERWATER OBJECT Russian patent published in 2005 - IPC

FIELD: systems of making positive floatation namely to systems ensuring making of carrying power with using rigid pontoons.

SUBSTANCE: arrangement of regulation of positive floatation of an underwater object has at least one tank cavity of which is fulfilled with possibility of infilling it with gas for making positive floatation with the help of the system of feeding gas. At least one valve is installed in the upper part of the mentioned tank. In the low part of the tank at least one hole connecting cavity of the tank with the water environment is made. The valve has a body with a saddle and a disc. The disc is firmly connected with a piston over which a chamber connected with the arrangement of forming control pressure is fulfilled.
