Abstract
A first valve chestformed integrally with a lidof a high-pressure gas cylinder, a first valve element, a spring, a second valve chest, a second valve element, a springand a main bodyare all formed in a rotor-shape, and in addition to arranging their axis lines on the same axis lime, flow channelsandare arranged on said axis line. By forming each part in a rotor-shape and adjusting the vibration directions of the valve elementsandto the same direction, miniaturization is contemplated while suppressing loads generated by vibration. This invention is to provide a compact two-step pressure-reducing valve usable for a long term.
