Abstract:
An emergency oxygen supply system is disclosed in which a oxygen tank and valve body are mounted on a bracket including a pin maintaining a valve within the valve body in a position blocking fluid flow from the tank to an oxygen mask. Flow of oxygen from the oxygen tank to the oxygen mask is automatically actuated upon removal of the tank and valve body from the bracket, since the pin remains with the bracket, and the valve no longer blocks fluid flow. The valve also provides pressure regulation to prevent overly high pressures from passing from the oxygen tank to the oxygen mask.
