To provide a pressure regulating valve reusable and excellent in economical efficiency and a capacitor provided with the same, and also, to provide a pressure regulating valve which can be reused in principle, which can regulate the pressure by being destroyed depending on modes of pressure fluctuations, and which is excellent in economical efficiency and high in safety; and to provide a capacitor provided with the same.
The pressure regulating valve is fitted in a valve hole 2a to be used for regulating the pressure and it can variably regulate the pressure by the pressure fluctuations. A mushroom shaped part 110, which is elastically and reversely deformed by the pressure, is provided on the surface of the valve hole 2a. A columnar part 120, which is integrated with the mushroom shaped part 110 and inserted to the valve hole 2a, is provided at the lower center of the mushroom shaped part 110. A collar part 130, which prevents from coming off, is provided on the rear face of the valve hole 2a at the end of the columnar part 120. And at the same time, a groove S for conducting the pressure to the inside 111 of the mushroom shaped part 110 is provided at the columnar part 120 and at the collar 130.
