Abstract
A gas generator having a reservoir from which liquid is fed to a gas generating chamber in selective feeding arrangements. In one method the liquid is poured into the reservoir for feeding at a decreasing pressure head. In a second selective feeding method a bottle of supply liquid is inverted in the reservoir for feeding at a generally uniform pressure head. In another method liquid is first placed in the reservoir and the inverted bottle is partially submerged in the liquid for initial feeding at a decreasing pressure head during depletion of the liquid in the reservoir between the bottle and the walls of the reservoir, followed by feeding at a generally uniform pressure head during depletion of liquid from within the bottle. The liquid can also be selectively fed by first filling the reservoir and then placing an inverted large bottle of liquid on top of the reservoir with the neck of the bottle submerged below the level of the liquid in the reservoir, resulting in initial feeding at a generally uniform pressure head during depletion of liquid from within the bottle, followed by feeding at a decreasing pressure head during depletion of liquid from the reservoir below the bottle.
