ABSTRACT:
The valve has a residual pressure valve (14) which is known per se, in which however the gas container can be filled through the residual pressure valve. The residual pressure valve (14) is mounted on a stem (32) which is axially displaceable as a result of a cam configuration in such a manner that it assumes a stable operating position under the influence of its spring (24) and an unstable open position under manual action on a filling apparatus (52) counter to the influence of its spring (24).
