ABSTRACT:
A pressure vessel (10) includes a tank (12) and a closure structure (14) with a breakaway part (90) exposed to fluid pressure in the tank (12). The breakaway part (90) is severable from the closure structure (14) for movement outward from the tank (12) under the influence of elevated fluid pressure. The pressure vessel (10) further includes a probe (144) which moves forcefully against and through the closure structure (14) to puncture a hole (210) through the breakaway part (90). The probe (144) guides the breakaway part (90) to move outward from the tank (12) telescopically over the probe (144) under the influence of the elevated fluid pressure.
