MULTI-CHAMBER GAS GENERATING SYSTEM

摘要

A multi-chamber gas generating system (10) has a housing (12) with openings (24) formed in a wall thereof. A gas-tight internal divider (42) separates the housing into two chambers (80, 80'). A gas generating sub-assembly (100) incorporating a baffle system is positioned in the first chamber (100). The sub-assembly (100) includes a first tubular member (44) and a second tubular member (52) positioned within the first member. The first and second members have openings (49, 54) formed therein to enable fluid communication between an interior of the second member (52) and the housing openings (24). The housing openings (24) are axially displaced from the first member opening (49) such that combustion products flow in a first axial direction between the first member opening and the housing opening. The first member opening (49) is axially displaced from the second member openings (54) such that combustion products flow in a second axial direction between the second member openings (54) and the first member opening (49). The second axial direction is substantially opposite from the first axial direction. A second sub-assembly (100') in second housing chamber (80') includes third and fourth tubular members (44', 52') similar to the first and second members and having openings therein axially displaced relative to each other such that combustion products flow in the second axial direction between the third member opening (49') and the housing openings (24), and in the first axial direction between the fourth member openings (54') and the third member opening (49').
