PROBLEM TO BE SOLVED: To enable gas supply to a fuel tank to be efficiently carried out.SOLUTION: There are provided: pressure accumulator detectors 17A and 17B for detecting pressure of gas in pressure accumulators 8A and 8B; inlet valves 11A and 11B for changing over the accumulated pressures to select any of a plurality of pressure accumulators 8A and 8B as accumulators for gas increased in pressure by a compressor 9; and a supply control device 18 acting as accumulator changing-over control means for controlling to change-over the inlet valves 11A and 11B in such a way that either the accumulator 8A or 8B filled with full-gas pressure first in these accumulators 8A and 8B is selected on the basis of pressures in the accumulators 8A and 8B detected by the accumulator pressure detectors 17A and 17B and capacities of the accumulators 8A and 8B and the gas increased in pressure by the compressor 9 is preferentially supplied to either selected accumulator 8A or 8B.SELECTED DRAWING: Figure 1 |
