DEVELOPMENT OF COMBINED AND PRESSURE-COMPENSATED, INHALATION-EXHALATION VALVE FOR PRESSURE BREATHING

Abstract

The development of smaller and lighter weight oxygen masks made necessary the design of a pressure-compensated, inhalation-exhalation valve to replace the three valves normally used in oxygen masks. The valve development program described was in two steps, i.e., the design of a valve with a convoluted compensating diaphragm and the modification of the valve by adding damping chambers and flow resistance reducing characteristics.
