Outline of Final Research Achievements

To develop vehicle radial slit type reducing valve, a small, radial slit was made. The flow rate characteristic was examined by using the equipment of hydrogen energy product research examination center (HyTReC) in Fukuoka. The height of the slit of a radial slit was made tens of micrometers, and the maximum pressure of the examination was adjusted to 35MPa. The mechanism of the flow was clarified by using the numerical analysis for the channel design of reducing valve to obtain the basic property. Radial slit type reducing valve that was able to throw flow rate 300l/min in pressure 35MPa was produced. The height of the space and length, etc. necessary for vehicle radial slit type reducing valve were clarified from the result of obtaining in the present study.
