PURPOSE: To automatically charge/discharge gas by attaching an inner pressure adjusting means to the lower part of a gas tank, dividing a gas charging line having a gas charging master valve so as to be connected to respective gas holders and also collecting gas discharge branch lines from each gas holder to a gas discharge line having a gas discharging master valve. ;CONSTITUTION: Inner pressure adjusting means 10 are attached to the lower part of a gas tank A-1 on a holder A side. A gas charge line 4 having a gas charging master valve 5 is divided and connected to respective gas holders A, B. Gas discharge branch lines 9, 9a are collected from respective gas holders A, B to a gas exhausting line 7 having a gas discharge master valve 8. Therefore, charge/discharge of gas can be automated between respective holders A, B by operating the gas charge master valve 5 and the gas discharge master valve 8 only one time, respectively, so that complicatedness to operate a valve can be solved.;COPYRIGHT: (C)1995,JPO
