ABSTRACT:
An apparatus and method for supplying oxygen to passengers on board an aircraft in the form of a portable machine including a housing having a shape and size allowing it to be positioned under a seat on the aircraft, an air separation device in the housing for separating oxygen from the air inside the aircraft, a self-contained compressed air supply in the housing including a compressor operatively connected to the air separation device and a brushless d-c motor for driving the compressor, and a circuit for connecting the d-c motor to the aircraft electrical power source including converting the a-c voltage and current on board the aircraft to d-c voltage and current for operating the motor. The brushless motor insures compliance with airline requirements that the machine generates a low level of electrical interference. The machine includes an intake resonator and a muffler associated therewith for reducing the level of noise generated to a value acceptable for airline use. The method and apparatus has the capability of delivering oxygen at various predetermined flow rates easily manually selected by the user. The machine preferably includes a PSA unit containing two beds and a four-way valve for connecting the compressed air supply to the beds in a controlled manner, the timing and control operating the system in a manner such that the four-way valve can be of the slide type with its advantages of long life and reliability.
