Title: GENERATOR, AIRBAG MODULE, VEHICLE SAFETY SYSTEM AND METHOD FOR PURIFYING A PYROTECHNICALLY PRODUCED GAS
Abstract:
The invention relates to a gas generator (10), particularly a pyrotechnical raw gas generator, with an axial longitudinal direction (L), comprising an ignition unit (20), a combustion chamber (30) axially mounted downstream from the ignition unit (20) and comprising a combustion chamber bottom (35) forming a combustion chamber outlet (36), and a filter chamber (70) that is axially mounted downstream of the combustion chamber (30). According to the invention, at least one guiding sleeve (50) and a front-side baffle plate (80) are formed in the filter chamber, a first end (51) of the guiding sleeve (50), on the side of the combustion chamber, being axially mounted downstream from the combustion chamber bottom (35), and a second end (53) of the guiding sleeve (50) being associated with the baffle plate (80), a first deflection section being formed on the baffle plate (80) and the guiding sleeve (50), which allows a gas flow to an outer side of the guiding sleeve (50) into an annular first discharge chamber (75).
