Abstract
A pressure vessel has an excess pressure release device comprising a passage between the interior and the exterior of the pressure vessel, a bursting disc seated in the passage, and a flexible membrane mounted adjacent to the disc between the interior of the vessel and the disc so as to seal the passage and hold the disc captive without the disc being clamped. The excess pressure release device may be used in connection with any pressure vessel requiring an excess pressure release device of the bursting-disc type. The device is particularly suitable for use in the dispensing valve of a home carbonation apparatus.
