Safety valve of the barometric type and pyrotechnic device comprising such a valve.

摘要

The safety valve (1) comprises a valve body (2), in which are formed a cylindrical chamber (3) extended parallel to the axis of a bore (16) intercepting a channel (12) connecting an inlet port (14) and a transverse outlet channel (15). A sealed manometric capsule (4) is seated in the cylindrical chamber, and a slide (17) is coupled to it and slides in the bore as a function of the deformations of the capsule. A bolt (19) extending in the channel normally prevents any communication between the inlet port (14) and the outlet channel, as long as the slide prevents any appreciable retraction of this bolt through the bore. This retraction is possible in particular positions of the slide. <IMAGE>
