IMPROVED BREATHING MASK AND REGULATOR FOR AIRCRAFT
摘要
The auxiliary breathing flow channel apparatus for an oxygen mask for pilots and crew of an airplane includes a flow control device with closed and open positions to regulate flow through an auxiliary channel. A pressure sensor such as an aneroid capsule automatically closes the auxiliary channel upon a decrease in cabin pressure. A handle also allows a user to manually move the flow regulating means to a closed position.
