ABSTRACT:
The electromechanical regulator for passenger oxygen is a hybrid oxygen regulator that provides for electronic or mechanical regulation of oxygen flow. The electronic portion of the regulator consists of an inlet solenoid valve, an outlet solenoid valve, a cabin pressure transducer, a regulated output transducer and a PID based controller, and the solenoid valves are normally biased so that in the event of an electronic system failure or a power supply failure the system will automatically revert to mechanical operation.
