FIELD: equalizing pressure values of oxygen and hydrogen in electrolyzer. SUBSTANCE: apparatus for equalizing gas pressure values in electrolyzers includes two vessels having inlet and outlet branch pipes and connected in their lower portions in such a way that to form communicated vessels. Upper portions of vessels over liquid level are mutually separated by means of elastic membrane joined with needle of valve of outlet branch pipe of one vessel. Apparatus allows to increase pressure difference between generated gases and atmosphere. EFFECT: enhanced accuracy of keeping equal pressure values of gases in electrolyzer. 2 cl, 1 dwg
