Abstract (en)
[origin: WO8002016A1] Regulation of the oxygen partial pressure in the closed respiratory circuit of a diver. A sample of the circuit gas mixture is continously taken; it is sent to the watch chamber (2) where the oxygen partial pressure thereof is measured and an electrical control signal is generated if the pressure measured becomes lower than an order value, and said signal is used to provoke an injection to the diver (4) of a determined amount of a gas mixture rich in oxygen. Application to diving in deep water.
