Abstract
A pressure-relief valve for an electrical capacitor which takes the form of a ring-shaped valve element of an elastic synthetic material which closes a valve opening in the housing of the capacitor. The valve member is held in position by a cylinder shaped part which has radial protuberances and which terminates in bulbous head. The bulbous head engages in snap-like fashion with a cooperable opening located in the housing of the capacitor. Suitable recesses are provided at the periphery of the cylindrical member to permit the valve to lift from its seat due to excess pressure within the capacitor.
