ABSTRACT:
A dual gas pressure vessel assembly comprising a pressure vessel shell, a piston dividing the interior of the shell into a first chamber and a second chamber, an exhaust passage leading from a portion of said first chamber spaced from the piston, a stop limiting movement of the piston towards the exhaust passage, and a burster disc in the piston. The piston carries frangible coupling means rigidly coupling the piston to the shell. In use the two chambers are respectively filled with the two gases required. When the exhaust passage is opened the first gas will be discharged from the first chamber, the piston will move against the stop and, when substantially all the first gas has been discharged, the burster disc will fracture, connecting the second chamber to the exhaust passage.
