摘要： A high-pressure switching valve device. A valve main body pressed to contact with an end face of a valve seat when the high-pressure switching valve device is closed, and a seal member pressed to contact with the end face of the valve seat when the high-pressure switching valve device is closed. When the high-pressure switching valve device is closed, the seal member is located on a high-pressure side and the valve main body is located on a low-pressure side.
