A gas generator has a tubular housing in which a combustion chamber containing a propellant charge, an outflow chamber and a clearance volume are disposed, positioned behind one another axially. A partition disk is provided between the clearance volume and the outflow chamber and has a central opening and an integrally formed tube section which surrounds the opening and extends to its free end away from the clearance volume towards the combustion chamber.

The invention claimed is: 1. A gas generator comprising a tubular housing (12) in which a combustion chamber (14) containing a propellant charge (18), an outflow chamber (20) and a clearance volume (32) are disposed, positioned behind one another axially, a partition disk (36) being provided betwee
The invention claimed is: 1. A gas generator comprising a tubular housing (12) in which a combustion chamber (14) containing a propellant charge (18), an outflow chamber (20) and a clearance volume (32) are disposed, positioned behind one another axially, a partition disk (36) being provided between the clearance volume (32) and the outflow chamber (20) and having a central opening (34) and an integrally formed tube section (40) which surrounds and defines the opening (34) and extends to its free end (39) away from the clearance volume (32) into the outflow chamber (20) towards the combustion chamber (14), wherein the partition disk (36) has several first flow-through openings (42) by means of which the clearance volume (32) is in direct fluid communication with the outflow chamber (20), wherein the tube section (40) has several second flow-through openings (44) by means of which the inside of the tube section (40) is in fluid communication with the outflow chamber (20). 2. The gas generator according to claim 1, wherein in the region of the outflow chamber (20), the housing (12) has several outflow openings (28), and the tube section (40) of the partition disk (36) extends axially, as observed from the clearance volume (32), into the outflow chamber (20) up to beyond the outflow openings (28). 3. The gas generator according to claim 1, wherein the tube section (40) extends axially over the whole length of the outflow chamber (20). 4. The gas generator according to claim 3, wherein the free end (39) of the tube section (40) rests against a separation wall (22) of the outflow chamber (20) near to the combustion chamber (14). 5. The gas generator according to claim 1, wherein the ratio of the total area of the second flow-through openings (44) to the total area of the first flow-through openings (42) is 10 to 50%. 6. The gas generator according to claim 1, wherein the first flow-through openings (42) are disposed near to outflow openings (28) which are formed in the housing (12) in the region of the outflow chamber (20). 7. The gas generator according to claim 1, wherein the second flow-through openings (44) are disposed a distance away from outflow openings (28) which are formed in the housing (12) in the region of the outflow chamber (20). 8. The gas generator according to claim 1, wherein the volume of the outflow chamber (20) is 10 to 50 of the volume of the clearance volume (32). 9. The gas generator according to claim 1, wherein the combustion chamber (14) has a separation wall (22) with at least one inflow opening (24), and at least one flow-through opening (34; 42, 44) is provided between the clearance volume (32) and the outflow chamber (20), the total area of the at least one inflow opening (24) being smaller than the total area of the at least one flow-through opening (34; 42, 44). 10. The gas generator according to claim 1, wherein a filter (30) is disposed in the outflow chamber (20). 11. The gas generator according to claim 1, wherein gas flowing into the clearance volume (32) can only leave the gas generator via the outflow chamber (20). 12. The gas generator according to claim 5, wherein the ratio of the total area of the second flow-through openings (44) to the total area of the first flow-through openings (42) is 30%. 13. The gas generator according to claim 1, wherein the volume of the out-flow chamber (20) is 30% of the volume of the clearance volume. 14. The gas generator according to claim 1, wherein the opening in the partition disk directs the gas to flow from the outflow chamber (20), into the clearance volume (32), and then back into the outflow chamber (20) before exiting the housing (12). 15. The gas generator according to claim 14, wherein the integrally formed tube section (40) directs the gas to flow both into and out of the clearance volume (32).
