Abstract
The invention relates to a gas generator for a safety system, in particular for a vehicle occupant restraint system, comprising a combustion chamber which contains propellant, a liquid chamber which contains liquid, and a mixing chamber in which a gas developed on burning of the propellant and the liquid mix with each other. The gas generator further comprises a liquid guide surface onto which the liquid when released is applied substantially tangentially, and a gas directing channel and a surface delimiting the gas directing channel. A flow break-off edge is provided in the mixing chamber, which flow break-off edge is defined on one side by the liquid guide surface and on the other side by the surface delimiting the gas directing channel. The gas directing channel directs a stream of developed gas into the mixing chamber at an angle of between approximately 60° and 120° with respect to the liquid guide surface in a region of the flow break-off edge, so that the liquid loosing from the flow break-off edge is entrained by the gas stream.
