摘要： An accumulator of the invention is provided with a safety mechanism for an emergency which releases an internal pressure of the housing to the oil port side so as to prevent the housing from being exploded by the internal pressure of the housing which comes to a higher pressure in an emergency, for example, occurrence of fire disaster. The safety mechanism for the emergency has a taper portion in a corner portion between the tubular portion and the end surface portion of the stay. The taper portion is buckled at its root position in the emergency. In the case that the taper portion is buckled, a pressure releasing flow path is formed between the bellows cap or the retained member and the taper portion as well as the bellows cap or the retained member and the end surface portion come away. The stay can be manufactured only by press molding.

摘要： In order to achieve an object to provide a liquid control valve of normally close valve type which has both of an outflow side pressure automatic regulating function and a water stop function, the liquid control valve has a pressure regulating piston which moves within a housing for finding a balance point between an outflow side pressure and a spring force of a pressure regulating spring placed so as to resist the outflow side pressure; a movable valve seat which is provided in the pressure regulating piston and moves together with the pressure regulating piston; and a valve body which sits on the valve seat so as to close the valve in accordance with a valve closing force generated by an inflow side pressure and a spring force of a water stop spring, and moves apart from the valve seat so as to open the valve at the time when an external valve opening force larger than the valve closing force is applied, whereby the outflow side pressure automatic regulating function is achieved in accordance with movement of the pressure regulating piston, and the water stop function is achieved in accordance with the valve close.
