PYROTECHNICAL GAS GENERATOR

摘要

The invention relates to a pyrotechnical gas generator (10) for actuating a cylinder (100), including a body defining a combustion chamber (12) which contains a main pyrotechnical load (14), and an igniter (16, 18) for initiating the combustion of said main pyrotechnical load (14). The pyrotechnical gas generator (10) includes at least one retarding chamber (22) suitable for communicating with the combustion chamber (12) via at least one inlet (62), and the retarding chamber (22) is provided with at least one outlet (63) for the passage of the gases outside the gas generator, wherein said outlet is provided with a seal (73) suitable for moving from a closed state to an open state when the pressure inside the retarding chamber reaches a maximum breaking pressure (P1).
