Title:
PRESSURE-REGULATING DEVICE, TRANSPORTATION VEHICLE, AND PRESSURE DIFFERENCE-CONTROLLING UNIT
Document Type and Number:
WIPO Patent Application WO/2004/050279
Kind Code:
A1
Abstract:
If an emergency stop is required during the supply of a pressurizing gas from a receiver tank into a container, a lever is turned to switch a three-way valve to a second mode. This causes a flow passage of a first valve port of the three-way valve to be closed, stopping the supply of the pressurizing gas from the receiver tank into the container. Further, because the gas can be communicated between a second valve port on the container side and a third valve port opened to air, the inside of the container is opened to air. This means that, in an emergency, one action of turning the single lever provided near an operator’s seat can simultaneously perform both stopping the supply of the pressuring gas from the receiver tank into the container and opening the inside of the container to air. Therefore, the safety of the system is very high.
