Abstract
The present invention discloses a flow-restricting filter capable of restricting intentionally the flow of the combustion gas from a solid propellant gas generator to an external member (for example, the nozzle) to rise up combustion pressure resulting in increasing a burning rate of the solid propellant and in reducing a burning area of the solid propellant and the overall size of the gas generator. The flow-restricting filter according to the present invention comprises a hollow member having a plurality of through holes formed thereon; and a flow-blocking plate provided at one end of the hollow member to form a space having one closed end and another opened end in the hollow member.
