ABSTRACT:
A valve useful for connecting a source of fluid under pressure to a using apparatus upon actuation of an explosive squib. The connecting structure includes an outer tube of soft material within which there is disposed an additional tube of brittle, frangible material having a reduced diameter area. The inner and outer tubes define an annular space surrounding an inner tubular space. One of the spaces is connected to the source of fluid under pressure, while the other of the spaces is connected to the using apparatus. Particularly, the inner tubular space is connected to a source of gas under pressure, while the outer annular area is connected to the using apparatus. Upon actuation of the squib the inner frangible tube is broken at the reduced diameter section upon a bending of the outer tube without its fracturing thereby connecting the source of fluid under pressure to the using apparatus, while at the same time isolating the products of combustion of the squib.
