<p>An accumulator provided with an emergency safety mechanism capable of being activated at a pressure lower than the pressure in the case in which a stay is provided with a rupture plate. An accumulator comprising: an accumulator housing; a stay having a liquid inlet/outlet provided in the end surface of the tip of a stepped tubular section of the stay; a bellows equipped with a bellows cap; a safety mechanism provided in preparation for pressure reduction; and an emergency safety mechanism configured in such a manner that, in an emergency such as occurrence of a fire, the bellows cap or a member held by the bellows cap is caused to press the stay by the pressure in the housing, said pressure being high due to the occurrence of a fire, to cause the stay to be buckled at the step, opening a liquid chamber. A thin-walled section is provided at a circumferential part of the step of the stay so that, in an emergency, the end surface of the stay can easily tilt when the stay is pressed by the bellows cap to be buckled at the step.</p> |
