Abstract

A gas generator for a safety system, in particular for a vehicle occupant restraint system, comprises a combustion chamber filled with propellant, in which a hot gas is generated after igniting and burning of the propellant, a fluid chamber containing a fluid, a mixing chamber in which fluid and hot gas are mixed in a mixture ratio, and at least one control device which controls the mixture ratio of fluid and hot gas in the mixing chamber.
