The main valve slides in the direction for its opening when the plunger is pushed in. This causes the nozzle hole and the main valve\s operating bore to be communicated, which then causes the compressed gas in a pressure vessel to open the follower valve\s check valve thus discharging the gas to the outside of the pressure vessel through the follower valve\s communicating bore. When the pressure at the discharge side exceeds the pressure of the pressure vessel during such discharge, a back-flow pressure causes the follower valve to slide, thus closing the follower valve\s operating bore and the communicating bore with the check valve. This closes the gas\s passage and prevents its back-flow into the pressure vessel. When charging a high-pressure gas, any moisture which has penetrated into the nozzle hole and/or the main valve\s operating bore can be blown off by discharging residual pressure in the pressure vessel.

In a valve arrangement to be attanched to a mouth tap secured to the opening of a pressure vessel, a valve arrangement characterized in that said valve arrangement comprises: a valve body which is screwed in and fixed at said mouth tap so as to close the passage of said mouth tap; a passage formed on the valve body composed of a nozzle hole, a main valve operating bore communicating with the nozzle hole, and a follower valve operating bore communicating with said main valve operating bore; a main valve mounted to be able to slide within said main valve operating bore, which is capable of opening and closing said nozzle hole but will not close said main valve operating bore; a pressure-exerting spring of the main valve provided within said main valve operating bore and applying force to said main valve in order to close said nozzle hole; a plunger which is integrally formed with said main valve and positioned within said nozzle hole; a fitting metal which is screwed in and attached to said valve body at the end of said follower valve operating bore and which includes a pass hole communicating with said follower valve operating bore; a follower valve mounted to be able to slide within said follower valve operating bore, said follower valve can open and close the passage between said main valve operating bore and said follower valve operating bore and said pass hole, but will not close said follower valve operating bore if either of the above is not closed; a communicating bore formed in the follower valve and communicating with said main valve operating bore and the pass hole of said fitting metal; a check valve which is provided within said communicating bore and permits gas to pass from the pass hole of said fitting metal to said main valve operating bore but prevents it from passing to the pass hole from said main valve operating bore; a pressure-exerting spring of the follower valve provided within said follower valve operating bore and applying force to said follower valve in such a direction as the passage between said follower valve operating bore and said main valve operating bore is closed; and a check valve operating rod which is secured to said main valve and releases said follower valve when it is extended towards said follower valve operating bore and the nozzle hole is opened with said plunger pushed in.
