ABSTRACT:
An apparatus and method for dispensing fluid including a pressure vessel at a first pressure and a reservoir at a second pressure. The reservoir communicates with the pressure vessel via a first aperture and with an environment at a third pressure via a second aperture. A reservoir vent having open and closed positions, that when opened the reservoir vents to a fourth pressure, and when closed the reservoir does not vent. A piston moveably disposed within the reservoir, and defines an aperture therethrough. A first burst seal disposed in the first aperture seals the pressure vessel from the reservoir, and engaged with the piston to be moveable therewith. A second burst seal disposed in the second aperture seals the reservoir from the environment. When the reservoir vents to the fourth pressure, the piston ruptures the second seal, and a first and third pressure difference ruptures the first seal.
