Abstract
An adjustable check valve for use in an oxygen regulator to establish limits at which a resiliently biased disc moves away from a seat to allow air to enter an atmospheric chamber. A regulator is connected to a linkage which operates an air flow valve and an oxygen proportioning flow valve. The regulator is responsive to inlet oxygen pressure such that a change in altitude causes a corresponding change in flow relationship of air through the air valve and oxygen through the oxygen valve.
