ABSTRACT:
The present invention relates to a valve assembly for an oxygen regulator. Two valves mounted in a housing supply oxygen and air flows to a manifold in the housing for subsequent delivery to a recipient's mask. The valves operate as electromechanical servoactuators. The nozzle of each valve serves as a magnetic pole for a surrounding voice coil bobbin. The bobbin fits over the nozzle and has a solid center portion adapted to seal the opening. When current is applied to the voice coil, a force is generated in the bobbin causing it to move toward or away from the nozzle. Movement of the bobbin away from the nozzle varies the opening of the valve and allows gas to be admitted into the housing. A linear variable differential transducer connected to the bobbin senses when proper displacement corresponding to valve opening is attained.
