FIELD: engines and pumps.
SUBSTANCE: proposed invention can be used for accumulation, storage, refrigeration and refueling of spacecraft tanks with preset parametres. Cryogenic refueling system comprises filling and discharging lines, unit of valves and accessories, pump-off unit and refueler with its chamber separated into three chambers, i.e. tank chamber, jacket chamber and heat-insulation chamber. This system is provided with service lines. Gas chambers of tank and jacket are inter-communicated by pipeline via pressure control valve to maintain pressure difference between tank and jacket at the level not higher than preset designed one.
EFFECT: expanded performances.
