FIELD: storage and delivery of gas. SUBSTANCE: proposed unit has main delivery line with electropneumatic valve, pressure reducer, safety valve and pressure relay mounted in succession and additional line with electropneumatic valve, pressure reducer, safety valve, pressure relay and drainage pipe lines mounted in succession; they are electrically connected with electropneumatic valves and interconnected by means of check valves. Proposed unit ensures continuous and automatic unattended maintenance of required parameters of compressed gas in preparing and launching launch vehicles and spacecraft. EFFECT: enhanced efficiency; avoidance of discharge of compressed gases into atmosphere. 1 dwg
