APPARATUS AND METHOD OF FLUID DELIVERY

摘要

Apparatus for gas delivery, particularly at low pressure and volume. The apparatus has a gas reservoir, a delivery line between the gas reservoir and a gas outlet and a first supply line between a first inlet connect able to a first gas supply and the gas reservoir. A pressure control line is provided with an inlet connect able to a second gas supply. The pressure control line is coupled to the gas reservoir to thereby control the pressure in the gas reservoir.
