Abstract

On décrit un dispositif (1, 2) de production de gaz (10, 20) qui comprend un premier compartiment (11, 21) contenant un premier réactif (13, 23) et un deuxième compartiment (12, 22) contenant un deuxième réactif. Le premier réactif (13, 23) est un matériau en écoulement et les deux réactifs produisent du gaz au contact l'un de l'autre. L'invention se caractérise en ce que le dispositif (1, 2) comprend en outre un sas (16, 26) pouvant être déplacé entre une première position dans laquelle il communique avec le premier compartiment (11, 21) et une deuxième position dans laquelle il communique avec le deuxième compartiment (12, 22). Ce dispositif fournit le propulseur nécessaire lorsqu'il est mis en oeuvre dans un contenant pressurisé. Dans un mode de fonctionnement, le contenant doit être équipé pour activer le générateur de gaz.
