The seawater valve is opened to flood the chamber. As the chamber floods, the air in the chamber is compressed until its pressure is equal to the sea pressure. When the pressure in the chamber is equalized with the sea pressure, the flooding of the chamber will stop. The water level must rise above the level of the escape tube (see diagram).

A diving chamber is a vessel for human occupation, which may have an entrance that can be sealed to hold an internal pressure significantly higher than ambient pressure, a pressurised gas system to control the internal pressure, and a supply of breathing gas for the occupants.
The "saturation system", "saturation complex" or "saturation spread" typically comprises either an underwater habitat or a surface complex which includesof a living chamber, transfer chamber and submersible decompression chamber, [45] which is commonly referred to in commercial diving and military diving as the diving bell, [46] personnel ...
In this test chamber, air pressure drops suddenly to that of the atmosphere at 60,000 ft (18,000 m). Air humidity immediately condenses into fog, which within seconds evaporates back into gas. The term uncontrolled decompression here refers to the unplanned depressurisation of vessels that are occupied by people; for example, a pressurised ...
The ASME definition of a pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. [2]The Australian and New Zealand standard "AS/NZS 1200:2000 Pressure equipment" defines a pressure vessel as a vessel subject to internal or external pressure, including connected components and accessories up to the connection to external ...
A deck decompression chamber (DDC), or double-lock chamber is a two compartment pressure vessel for human occupation which has sufficient space in the main chamber for two or more occupants, and a forechamber which can allow a person to be pressurised or decompressed while the main chamber remains under constant pressure.
A diaphragm separates a pressure chamber from the main water supply. A narrow passageway leads from the main water supply into the pressure chamber. It is the narrowness of this passage that meters the flow by slowing repressurizing of the pressure chamber after the action of a flush.
