  • Patent number: 10781935
    Abstract: A valve operating member includes a valve support portion, which supports a valve disk while allowing the valve disk to move relative to the valve operating member in a direction of an axis. An elastic member is disposed inside a valve chest. The elastic member constantly urges the valve disk toward the valve seat in the direction of the axis to cause the valve disk to be seated on the valve seat with an urging force. The valve support portion includes a valve engagement portion, which is engaged with an engaged portion of the valve disk seated on the valve seat, and separates the valve disk apart from the valve seat. When the valve disk is seated on the valve seat, the valve engagement portion is not in contact with the valve disk in the direction of the axis.
