Abstract:
(EN) The invention relates to a gas generator (10), comprising an ignition unit (30) with an igniter (31), a chamber (20) which is axially downstream of the ignition unit (30) and a diffuser chamber (40) which is surrounded by a diffuser (42) and which axially downstream of the chamber (20). A combustion chamber sieve (50) with an ignition-sided end (51) and a diffuser-sided end (52) is arranged in the chamber, said combustion chamber sieve (50) extending in the longitudinal direction (L) of the gas generator (10), starting from the igniter (31) towards the diffuser (42), tapering, in particular conically.
(FR) L'invention concerne un générateur de gaz (10), comprenant une unité d'allumage (30) équipée d'un allumeur (31), une chambre (20) montée axialement en aval de l'unité d'allumage (30) et une chambre de diffuseur (40) qui est montée axialement en aval de ladite chambre (20) et qui est entourée par un diffuseur (42), un tamis de chambre de combustion (50) présentant une extrémité côté allumeur (50) et une extrémité côté diffuseur (52) étant disposé dans la chambre (20), ce tamis de chambre de combustion (50) s'étendant en s'amincissant, en particulier de manière conique, dans la direction longitudinale (L) du générateur de gaz (10), à partir de l'allumeur (31) jusqu'au diffuseur (42).
(DE) Die Erfindung betrifft einen Gasgenerator (10), umfassend eine Anzündeinheit (30) mit einem Anzünder (31), eine der Anzündeinheit (30) axial nachgelagerte Kammer (20) und eine der Kammer (20) axial nachgelagerte Diffusorkammer (40), die von einem Diffusor (42) umfasst ist, wobei in der Kammer (20) ein Brennkammersieb (50) mit einem anzünderseitigen Ende (51) und einem diffusorseitigen Ende (52) angeordnet ist, wobei das Brennkammersieb (50) in Längsrichtung (L) des Gasgenerators (10), ausgehend von dem Anzünder (31) hin zu dem Diffusor (42), verjüngend, insbesondere konisch, zuläuft.
