The proposed utility model relates to a movable motor gazozapravschikam (hereinafter - PAGZ) intended for refilling consumer, for example, locomotives, boilers and the like, compressed natural gas (CNG). The technical problem is to increase the convenience and efficiency of refueling.; PAGZ assembly 1 comprises a gas cylinder for filling the CPG system from an external source. Gas bottle system comprising two gas cylinders connected pipes in independent sections 3, 4, 5. The automatic refueling system comprises a switching unit 7, the sensors 8 for measuring the gas pressure, the solenoid valves 9, gazorazdatochnuyu column 10. Accounting Subsystem comprises the automatic gas flow meter 13, an arithmetic device 14, the information board 15. PAGZ also equipped with a compressor. a compressor input coupled to the gas balloon sections 3-5. Compressor output is connected to the column 10.; In the first stage charging section 3, 4, 5 is connected in turn to the reservoir 18. The user with each new connection is compressed gas in the tank to a higher value according to the principle of communicating vessels. In the second stage compressor is used, which pumps gas residues from the sections 3-5, compresses them and pumping consumer. At each stage of the flow meter 13 takes into account the volume of gas, provide the consumer, and the processor 13 calculates the price of gas, and outputs the sum to pay on the scoreboard 15.; 5-n in f-ly 1 Fig.
