ABSTRACT:
An apparatus includes a pressure vessel with a closure structure (14) including a part (62) consisting of a single, continuous body of homogeneous metal material. The part (62) has a plurality of fluid outlet openings (22), a fluid outlet conduit (88) communicating with the outlet openings (22), and a pocket (100) separate from the outlet conduit (88). The pocket (100) has a closed inner end (116) defined by a thin wall portion (120) of the part (62). An initiator (40) is received in the pocket (100), and is actuatable to rupture the thin wall portion (120) of the part (62). In a preferred embodiment, a retainer structure (102) holds the initiator (40) in the pocket (100). The retainer structure (102) and the part (62) have adjoining, unthreaded surfaces (160, 108) engaging each other in an interference fit which is tight enough to hold the retainer structure (102) and the initiator (40) in the pocket (100) when the initiator (40) is actuated.
