Anti-Suffocation Valve Bendix Type Number 3267010-0101.

摘要

The oxygen supply currently located in the RSSK (Rigid Seat Survival Kit) provides the aircrewmember with an emergency source of oxygen in the event of an in-flight failure of the aircraft oxygen system, during parachute descent, or in the event of aircraft ditching. An inherent danger in the system is the suffocation of an unconscious aircrewmember who cannot remove his mask in the event the emergency oxygen supply becomes depleted or is malfunctioning. The protection envelope currently provided the aircrewmember will be greatly enhanced through the incorporation of an anti-suffocation valve, providing the capability of breathing ambient air when oxygen from the emergency supply is no longer available. The valve overcomes the danger of an aircrewmember unknowingly breathing air during normal in-flight operation, and prevents the entrance of water during an underwater or flotation condition. (Author)
