摘要： PURPOSE:To reduce the weight of a housing by a method wherein the outer end of a closure is securely welded to the extension part of a diffuser to form a filter coolant chamber, and an outflow port for gas from the filter coolant chamber is formed in the extension part of the diffuser. CONSTITUTION:A disc-shaped diffuser 12 having an extension part overlapped with a central holder 4 and the top wall on the passenger side of a combuster cup 14 is arranged to the outside of a combustion chamber housing. An annular closer 17 is arranged in a state to be overlapped with the top wall on the opposite side of the combustor cup 14. A filter coolant chamber (expansion chamber) 18 in which a filter coolant is arranged is composed of the extension part of the diffuser 12 and outer peripheral flange 15 of the closure 17. The outer peripheral edge of the outer peripheral flange 15 is securely welded to the inner peripheral edge of the lower end of the extension part of the diffuser 12 and the inner peripheral edge of the closure 17 is securely welded to the outer peripheral edge of the lower end of a central holder 4 togetherwith the inner peripheral edge of a cover 16.

摘要： PURPOSE:To provide a sheet structural gas generator that is ameliorated of its housing strengtheningly, and able to seal in a gas generating medium through a nonwelding process, so advantageous from the standpoint of manufacturing equipment in addition to lightweightiness. CONSTITUTION:A combustion chamber 10 is formed by a cumbustor cup 14 with a ring top face whose inner edge is clamped to a top wall peripheral edge of a central tubular holder 4 by means of riveting 28. There is provided a combustor plate 16 being welded to a peripheral flange inner edge of the combustor cup at an outer edge in order to close this combustion chamber and welded to an opposite end edge part of the holder at the inner edge, and further it has a diffuser 12 which covers a top wall of the central tubular holder and a top face of the combustor cup to be connected to this top wall, thereby forming a double wall surface, thus an end edge of the peripheral flange 15 of the combustor cup is constituted so as to be welded to an inner wall of an extension part of the diffuser.
