Abstract
A valve device includes a body having a gas flow path. 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 opens a valve when the gas is charged and closes the valve when the gas charge is completed, and the drive mechanism opens the valve of the check valve mechanism and holds the open state of the valve of the check valve mechanism when the gas is discharged from the tank. The check valve mechanism includes a valve seat, and the valve seat is disposed in the first flow path.
