气体充填装置包括气体流路，其包括可连接气体供给源的流入端和可连接压力蓄积器的流出端，压缩机，存储部和进行第一压缩的操作控制部 从与流入端连接的气体供给源供给的气体由压缩机压缩而从流出端排出的第二压缩填充动作，存储在存储部的气体被压缩机压缩的第二压缩填充动作， 从流出端排出，操作控制部进行第一压缩填充操作，直到流出端处的气体的压力达到预定压力，并执行用于将第一压缩填充操作转换到第二压缩填充操作的控制，当第二压缩填充操作 压力达到预定压力。

An object of the present invention is to prevent the gas becomes a charge control to the accumulator by the gas filling device complicated.
Gas charging device 10 is a gas source 25, a connectable inlet end (16e) and the accumulator (12a) connectable outlet end with a gas distributor 16 having a (16h), the compressor (18), and , and a storage portion 20, a driving control section (22a). Driving control section (22a) is first compressed charge operation and a storage portion is compressed by the gas supplied from the gas supply source 25 is connected to the inlet end (16e) of the compressor 18 for flowing out of the outlet end (16h) ( the gas in the reservoir 20) is compressed by the compressor 18 to perform the charging operation to the second compression flowing out of the outlet end (16h). Driving control section (22a) is subjected to a first compression filling operation until the gas pressure at the outlet end (16h) to be a predetermined pressure, when it reaches the predetermined pressure, and executes a control to switch to the second compression filling operation.
