AN AIR-OXYGEN MIXING VALVE FOR VOLUME-CYCLED RESPIRATORS

Abstract

A valve that can deliver breathing gas of variable air-oxygen makeup to respirators has been designed, fabricated, and tested. Test results show that gas mixtures containing 20 to 100 percent oxygen can be obtained with good reliability. The maximum change in the makeup of gas leaving the valve caused by varying test conditions was about 5 percent oxygen.
