  • Closed cycle respirator with emergency oxygen supply
    Patent number: 4423723
    Abstract: A closed cycle respirator with emergency oxygen supply is disclosed which comprises a main oxygen flow path from an oxygen bottle into a breathing bag of the closed breathing cycle. A switching valve is provided in the first path and branches off into a second path also for supplying oxygen into the bag. The first oxygen flow path has a solenoid valve therein which is controlled by a first oxygen sensor in the breathing bag. The switching valve is controlled by a second oxygen sensor in the breathing bag for switching oxygen supply over to the second flow path in case the solenoid valve malfunctions or anytime the oxygen in the bag falls below or rises above a set desired limit.
