METHOD AND DEVICE FOR FILLING COMPRESSED GAS INTO VESSELS

摘要

The invention describes a method and device for filling compressed air into vessels by means of feeding, from an accumulator (1), filling gas doses of a desired pressure while controlling and stabilizing the gas pressure within a range between given minimum and maximum values. The stabilization of the gas pressure is effected by simultaneous pumping of the compressed gas into the accumulator (1) during the bleed-off of the gas from it in the course of filling in vessels (13), and charging in or discharging from the accumulator (1) a liquid by means of a pump (15) or a pumping-compressing unit. The charging of the liquid is effected in case of a gas pressure drop in the accumulator (1) below the given minimum value, whereas the discharging of the liquid is effected in case of exceeding its given maximum value.
