Patent ID: 8100670

Claim:
A device for propelling a liquid comprising: a reservoir in which to store said liquid at its saturation vapor pressure, equipped with a means for delivering said liquid once pressurized; a pyrotechnic gas generator arranged inside said reservoir to pressurize said liquid inside said reservoir and propel it once pressurized out of said reservoir, via said open delivery means; said gas generator having a body of cylindrical geometry capable of accommodating and holding in a stable manner a pyrotechnic charge that can burn within it, generating combustion gases, with nozzles, at least some of which are initially completely obturated by obturating means capable of rupturing under the pressure of said generated combustion gases, so as to deliver said combustion gases under pressure; a mobile separation member arranged inside said reservoir to separate said liquid from said generator and from said generated combustion gases; wherein said nozzles of said gas generator are arranged radially on the wall(s) of said body, and in that said gas generator, arranged in such a way that its axis corresponds to the line of travel of said mobile separation member, is equipped with a deflector to deflect said generated combustion gases along said line of travel of said mobile separation member.
