US5042473A - Demand valve for a respirator - Google Patents

A demand valve for a respirator. A fixed tube directs pressurized air flow from the source into an opening for a mask. The venturi effect caused by directed air flow through the housing acts to draw the diaphragm toward the respirator face mask. A portion of the air directed by the tube escapes and is directed over the tube by a hinged three sided arm.
