Document Type and Number:
Japanese Patent JPH0562373
Kind Code:
B2
Abstract:
An oxygen partial pressure controller regulates the oxygen partial pressure (PP02) of the product gas of a pressure swing adsorption oxygen enriching system by means of a bleed valve (16) which increases gas flow through the adsorptive system thereby decreasing the PP02 of the product gas. The controller includes a solenoid valve (28) which permits the bleed valve (16) to function when the adsorption system pressure and PP02 is high. An aneroid (36) controls the product gas flow as a function of altitude when the bleed valve (16) is permitted to function.
