Abstract

Abstract A mechanical ignition gas generator including a housing which consists of an upper outer shell container (diffuser) (1) and a lower outer shell container (closure) (2) fitted to each other in such a manner as to define an annular space for storing therein a gas generating agent, a priming charge, a cooling material and a filter, in which said annular space comprises a priming charge chamber (9) for storing said priming charge and in which said closure has a shaped space (20) for receipt and storage of, a correspondingly shaped mechanical igniter (12) in its lower surface and a plurality of caps (3) each ignitable by an ignition pin (15) of said ignitor (12) are disposed on the top wall of said shaped space (20), cap holes (18) being provided in closure (2) for communicating the back surface of each of said caps (3) with said priming charge chamber (9) characterised - that a hole(s) (32) for communicating the priming charge chamber (9) with the front surface of each said caps (3) is disposed inside said closure (2) of said housing.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 181 words
A mechanical ignition gas generator including a housing which consists of an upper outer shell container (diffuser) (1) and a lower outer shell container (closure) (2) fitted to each other in such a manner as to define an annular space for storing therein a gas generating agent, a priming charge, a cooling material and a filter, in which said annular space comprises a priming charge chamber (9) for storing said priming charge and in which said closure has a shaped space (20) for receipt and storage of, a correspondingly shaped mechanical igniter (12) in its lower surface and a plurality of caps (3) each ignitable by an ignition pin (15) of said ignitor (12) are disposed on the top wall of said shaped space (20), cap holes (18) being provided in closure (2) for communicating the back surface of each of said caps (3) with said priming charge chamber (9) characterised - that a hole(s) (32) for communicating the priming charge chamber (9) with the front surface of each said caps (3) is disposed inside said closure (2) of said housing.
Claim 2
Dependent Claim 181 words
A mechanical ignition gas generator including a housing which consists of an upper outer shell container (diffuser) (1) and a lower outer shell container (closure) (2) fitted to each other in such a manner as to define an annular space for storing therein a gas generating agent, a priming charge, a cooling material and a filter, in which said annular space comprises a priming charge chamber (9) for storing said priming charge and in which said closure has a shaped space (20) for receipt and storage of, a correspondingly shaped mechanical igniter (12) in its lower surface and a plurality of caps (3) each ignitable by an ignition pin (15) of said ignitor (12) are disposed on the top wall of said shaped space (20), cap holes (18) being provided in closure (2) for communicating the back surface of each of said caps (3) with said priming charge chamber (9) characterised - that a hole(s) (32) for communicating the priming charge chamber (9) with the front surface of each said caps (3) is disposed inside said closure (2) of said housing.
Claim 3
Dependent Claim 76 words
The generator as claimed in Claim 1, characterised - that there is an annular pressure partition (combustion ring) 130 for dividing a gas generating agent chamber, a cooling material chamber and a filter chamber, a belt-like gas generating agent container reception portior (115) extending inwardly in a radial direction is disposed on said pressure partition, and a large number of notches (121) in a circumferential direction are formed throughout the entire periphery of said reception portion.
Claim 4
Dependent Claim 53 words
The generator as claimed in Claim 1, characterised - that an annular gas cooling material is disposed in a cooling material chamber disposed outwardly in a radial direction of a gas generating agent chamber and has a shape such that its inner lower part is notched in the section in the radial direction.
Claim 5
Dependent Claim 88 words
The generator as claimed in Claim 1, characterised - that said gas generating agent (321) is stored in a container (313) having a shape fitting to said annular space, the cover (326) of said container (313) is fixed and sealed by caulking the inner and outer cylindrical walls of a container main body, and an annular flexible member (314) is disposed between said cover (326) of said gas generating agent container (313) and the opposed surface of said diffuser (1) in order to prevent oscillation of said container.
