Abstract: When emergency shutdown operation becomes necessary while a gas used for applying pressure to the in of the container is being supplied from the receiver tank to the container, the lever is turned and the three-way valve is switched to the second mode. Then the first valve opening in the three-way valve is blocked and the supply of the gas used for applying pressure to an inside of the container from the receiver tank to the container is stopped. In addition, since the gas can flow between the second valve opening on the container side and the third valve opening opened to an atmosphere in the container is released to an atmosphere. In other words, in the present invention, the supply of the gas used for applying pressure to the in the container can be stopped and, in the same time, in the container is released to the atmosphere with a single action, namely, manually turning the lever provided close to the driving seat. Therefore, the safety level of the system is very high.
