ABSTRACT:
A first valve chest241formed integrally with a lid2of a high-pressure gas cylinder, a first valve element5, a spring6, a second valve chest32, a second valve element7, a spring8and a main body8are all formed in a rotor-shape, and in addition to arranging their axis lines on the same axis lime, flow channels56, 35and76are arranged on said axis line. By forming each part in a rotor-shape and adjusting the vibration directions of the valve elements5and7to 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.
