Abstract
A valve assembly with a check valve for a gas container has a check valve chamber formed in such a portion of a circumferential wall of a stop valve chamber within a valve box as being adjacent the portion on the side of a stop valve opening and closing manipulation assembly and the portion on the side of a gas outlet port. Within the check valve chamber a check valve body is resiliently urged to a check valve seat for valve closing by means of a checking spring. A check valve body opening member for opening the check valve body is arranged so as to face the check valve body from the side of the check valve seat and is adapted to be advanced toward the check valve chamber so as to be changed over to the valve open position for opening the check valve body and to be retreated from the check valve chamber so as to be changed over to the valve opening cancellation position.
