VALVE SYSTEM OF HIGH PRESSURE TANK FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To cope with miniaturization, while securing conventional functions, in a valve system of the high pressure tank for a vehicle.SOLUTION: This valve system 10 includes a fusible plug valve 34 including a fusible plug valve function of opening at a high temperature to release gas from the high pressure tank 12 to the outside and a manual valve function of releasing gas from the high pressure tank 12 to the outside by manual opening. Two kinds of valves of the fusible plug valve 34 and a manual depressurization valve therefore are not required to be separately provided, and further a communication passage for communicating an inflow passage 18 with an outflow passage 20 can be eliminated. As a result, the valve system 10 can be made smaller than a conventional valve system.
