Abstract
A dual gas pressure vessel is divided into a first chamber 22 and a second chamber 24 by collapsible bellows 16. As the gas in the first chamber is dishcarged through an exhaust 29 the bellows collapse until a plate 20 is pierced by a probe 32, following which the gas in the second chamber 24 is vented. A support 26 for the plate 20 ensures that, during charging of the vessel, the first and second chambers are well defined in volume.
