Abstract
A communication hole, which communicates with a primary-side portand a secondary-side port, is opened and closed by a valve elementcontacting with a valve seat, and a spring force in a direction of contacting with the valve seatis applied to the valve elementby a valve spring. A pressure-regulating diaphragmis mounted in a housingopposite the valve element, and a spring force in a direction of opening the valve elementis biased to the pressure-regulating diaphragmby a pressure-regulating spring. A tip facethat opens and closes a relief holeis provided, and a stemthat converts, to the valve element, a movement of the pressure-regulating diaphragmtoward the valve elementis provided in the valve element. The pressure-regulating diaphragmis provided with a dynamic-vibration absorbing apparatus, which suppresses a vibration of the pressure-regulating diaphragmat an exhausting time of being exhausted from the relief hole, and vibrations of a diaphragm assemblyand a valve assemblyat a pressure-regulating time.
