ABSTRACT:
The pyrotechnic valve according to the invention comprises one or more pyrotechnic devices able to produce gases under a high pressure, which has the effect of suddenly deforming a membrane equipped with a rigid weight. The latter projects a punch, which shears a tight end fitting, thus freeing the fluid passage. The membrane ensures a perfect seal between the fluid circulation zone and the zone containing the gases produced by the pyrotechnic devices.
