    • PROBLEM TO BE SOLVED: To provide a solenoid valve device for a high-pressure fluid capable of being physically miniaturized while blocking or permitting flow of the high pressure fluid.SOLUTION: A movable core 30 reciprocating in a guide cylinder 20 has a small outer diameter portion 301, a large outer diameter portion 302 and a projecting portion 303. When a magnetic circuit is formed by power distribution to a coil 41, magnetic attraction force inclined with respect to a central axis φ is generated between the guide cylinder 20 and the movable core 30, and the movable core 30 is attracted to a fixed core 35. The movable core 30 is brought into contact with an inner peripheral face of the guide cylinder 20 at a sliding portion 33 disposed on an outer periphery of the small diameter portion 301 and the projecting portion 303, and a clearance gap is formed between an outer peripheral face of the movable core 30 excluding the projecting portion 303, and an inner peripheral face of the guide cylinder 20. Thus, magnetic attraction force generated vertically to the central axis φ is reduced, and frictional resistance with respect to the guide cylinder 20 of the movable core 30 is reduced. Therefore, a valve can be opened with small magnetic attraction force, so a coil assembly 40 can be miniaturized.
    • 要解决的问题:提供一种能够在阻塞或允许高压流体流动的同时物理地小型化的高压流体的电磁阀装置。解决方案:在引导筒20中往复运动的可动芯30具有小的外径 部分301,大外径部分302和突出部分303.当通过对线圈41的配电形成磁路时,相对于中心轴线倾斜的磁吸引力 在导向筒20和可动芯30之间产生可动芯30,并且可动芯30被吸引到固定芯35.可动芯30在设置的滑动部33与导向筒20的内周面接触 在小直径部301的外周和突出部303之间,在可动芯30的除了突出部303的外周面与引导筒20的内周面之间形成间隙。因此, ,垂直于中心轴产生的磁吸引力 并且相对于可动铁芯30的引导筒20的摩擦阻力减小。 因此,能够以小的磁力吸引力打开阀,因此能够使线圈组件40小型化。

    • PROBLEM TO BE SOLVED: To provide a fuel gas supply system capable of precisely controlling supply pressure to a fuel gas consuming apparatus in a wide range from a small flow rate to a large flow rate without performing complicated pressure control and with a simple system configuration.SOLUTION: The fuel gas supply system 1 is configured such that a fuel gas in a high-pressure tank 3 is supplied to the fuel gas consuming apparatus 2 through a supply path 4, wherein the supply path 4 is branched into first and second flow channels 11, 12, and then the flow channels are joined together to be one joined flow channel 14. The first flow channel 11 is provided with an electromagnetic on-off valve 6 that opens and closes it, and the second flow channel 12 is provided with an electromagnetic pressure-regulating valve 7 for regulating pressure of the fuel gas flowing therein. Then, the electromagnetic pressure-regulating valve 7 is configured such that the Cv value thereof is smaller than the Cv value of the electromagnetic on-off valve 6.
