ABSTRACT:
There is provided a pressure accumulator system comprising a plurality of small-sized gas bombs connected. This dispenses with any large-sized gas bomb that is hard to handle. The pressure accumulator system comprises a plurality of gas bombs each having an ejection port sealed by a membrane member, a membrane-breaking mechanism mounted in the ejection port of each of the gas bombs and operated in accordance with a given electrical signal to force the membrane member of the gas bomb to break, a sequencer for sending an electrical control signal to the membrane-breaking mechanisms to activate them, and a pressure sensor mounted in a conduit communicating the gas bombs and an actuator for producing an output signal to the sequencer. The sequencer is operated according to the output signals from the pressure sensor and, when the pressure inside any one of the gas bombs becomes lower than a present pressure.
