RATIO AND DILUTION VALVES LOW PRESSURE OXYGEN
Abstract
Altitude controlled oxygen regulators designed for use with partial pressure suit helmets supply 100 percent oxygen at a fixed pressure above ambient pressure. This type of regulator could not be used with a standard pressure breathing oxygen mask. To negate the need for a dual oxygen regulator system, i.e., one for suit helmets and one for oxygen masks, a low pressure ratio valve was designed. Th valve was later modified to permit oxygen delivered by the r gulator to be dilut d with ambient air. The modified valve provided the pressure reduction required for the mask and extended flight range by conserving oxygen. The valve can be fabricat d as (1) a low pressure ratio valve, (2) a combination diluter and low pressure ratio valve, and (3) a diluter valve. (Author)
