An inflatable article adapted for automatic inflation, for example a life jacket, an inflatable suit, or a life raft. The article has a compressed gas cylinder for inflating the article with a gas, and a diaphragm for comparing the ambient fluid pressure with the internal gas pressure in a closed flexible compartment such as the internal space of the article and for activating the article automatically when the ambient fluid pressure exceeds by a predetermined amount the internal gas pressure in the compartment. |
