Abstract

La pr esente invention se rapporte aux dispositifs de d epressurisation rapide de r eservoirs de gaz sous pression notamment utilis es comme dispositifs d'arrêt de pouss ee sur les propulseurs à propergol solide.La pr esente invention concerne plus pr ecis ement un dispositif de d epressurisation rapide d'un r eservoir (1) comprenant au moins une pièce (2) constituant un bouchon d'obturation. Les deux principales caract eristiques de ce dispositif sont, d'une part, qu'un piston (3) coopère à la fixation de la pièce (2) sur le r eservoir (1) et, d'autre part, qu'une canalisation (4) connect ee au r eservoir (1) de gaz et comprenant un dispositif d'ouverture cr e ee, lorsqu'elle est ouverte, une circulation parallèle de gaz sous pression induisant le d eplacement du piston (3) qui libère la pièce (2) et provoque son ejection.Un avantage important procur e par ce type de dispositif est qu'il evite d'avoir à utiliser des charges pyrotechniques explosives directement au contact du r eservoir (1).
