  • Apparatus for automatic inflation of diver flotation means
    Patent number: 4176418
    Abstract: Apparatus for automatic inflation of a diver flotation device in response to cessation of breathing by the diver, or in response to pressure reduction of the air source to a predetermined reserve pressure. The apparatus includes high and low pressure systems, the low pressure system being coupled to the diver flotation device and to the diver breathing device. A pair of valves interposed between the high and low pressure systems are responsive to termination of diver breathing and reduction of the source pressure to a predetermined reserve pressure, respectively, to open and allow air from the high pressure system to pass into the low pressure system. This inflates the flotation device and brings the diver to the surface.
