摘要:
A gas release device that includes a reservoir of pressurised gas and a passageway fromsaid reservoir to an outlet. There is an elastic gas permeable membrane in thepassageway that allows gas release only via the membrane. A gas impermeable memberis provided in the passageway that includes an interface positioned to contactsaid gas permeable membrane. Displacement of the gas permeable membrane is responsiveto the pressure of the gas in the reservoir such that there is a greater interfacialcontact between the gas impermeable member and the gas permeable membrane ata higher gas pressure than at lower pressure to thereby vary the exposed crosssectional area of the permeable membrane available to the flow in an inverse relationshipto pressure.
