Abstract
Abstract A gas-generating valve for releasing a pressurized fluid from a container and releasing a gas into the fluid from a gas generator after the fluid has been released. This is accomplished by opening an outlet port on the container, preferably by the action of a piston moving relative to a casing. Gas from the gas generator is then released into the fluid, again preferably by the movement of the piston.
