Abstract
An oxygen regulator for controlling the flow of breathing oxygen and uncontaminated air at various altitudes includes a balanced oxygen valve (20) and a balanced air valve (50) which cooperate with a dilution aneroid valve (62) to provide breathable mixture whose oxygen percentage increases with altitude to a predetermined altitude. Above that altitude one hundred percent oxygen is provided. A gas loading aneroid valve (110) operates to increase the oxygen pressure in accordance with altitude over a range of altitude.
