The invention concerns a gas generator with a fuel gas filter for the pyrotechanical production of gases from a propellant charge. A separator chamber is disclosed that is designed with annular slots for the purpose of cleaning gas contaminated with solid residue from combustion. The gases produced in the combustion chamber enter the separator chamber through tangentially arranged gas ducts. After flowing through the annular formed separator chamber, the gases flow around the frontal area of the central axially arranged center block before they reach the guidance components, which are sensitive to soiling. Subsequently, the hot gases exit by way of a jet. Through the effect of centrifugal forces, the contaminating particles are slung against the outer wall of the annularly slotted separator chamber and are held fast in its special profile.
