Valve device

A valve device comprising a body, the body having a gas flow path, wherein:

• the valve device is for a high-pressure gas tank;
• the gas flow path is configured to allow communication between an inside and an outside of the high-pressure gas tank, and is configured to be commonly used when gas is charged into the high-pressure gas tank and when the gas is discharged from the high-pressure gas tank;
• the gas flow path has a first flow path, a second flow path, and an intersecting portion in which the first flow path and the second flow path intersect each other outside of the high-pressure gas tank, and when the gas is charged, the first flow path is located upstream of the intersecting portion, and the second flow path is located downstream of the intersecting portion;
• the gas flow path has a check valve mechanism and a drive mechanism, the check valve mechanism is configured to open a valve when the gas is charged and close the valve when gas charge is completed, and the drive mechanism is configured to open the valve of the check valve mechanism and hold an open state of the valve of the check valve mechanism when the gas is discharged from the high-pressure gas tank;
• the check valve mechanism includes a valve seat, the valve seat being disposed in the first flow path;
• the valve has a main valve that opens and closes the valve seat;
• and
• the intersecting portion includes a point at which a first axis of the first flow path and second axis of the second flow path intersect, and the point is within the main valve.
