RESCUE UNDERWATER APPARATUS Russian patent published in 2019 - IPC B63G8/41 

FIELD: shipbuilding.

SUBSTANCE: invention relates to rescue submersibles, designed to rescue crews of emergency submarines. Rescue underwater vehicle, having a control compartment for accommodating the crew of the apparatus and a rescue compartment for accommodating the rescued submariners, is equipped with tanks, one of which withstands full outboard pressure. Tanks through valves are connected by a system having a pump capable of creating a pressure equal to the total outboard pressure. Device has the ability to remove air from the rescue compartment overboard, with the completion of the removed air from the air supply in the cylinder or cylinders. To remove air overboard, the means of the above system and two tanks are used, one of which withstands the full outboard pressure.

EFFECT: ensuring that air is removed from the compartment overboard, including air polluted with carbon dioxide, which is possible at any depth, this increases the maximum possible residence time in the compartment, for example, in the event of a vehicle accident and the inability to ascend by its own means.
